Expected Result
The frozen enemy thaws and its behavior resumes as normal.

It should include a programming style guide, a summary of our submission policies, and anything else that may minimize merge conflicts in the future.
Environment:
Steps To Reproduce
Expected Result
The game runs smoothly; there are no instances of excessive slowdown or performance degradation.
Observed Result
There are moments when the game slows down excessively, negatively affecting play.
Additional context
The slowdown was confirmed by @AlexKhayrullin. A quick look at the profiler showed this:
Updating objSeabot's code has already been proven to work, but other, more subtle changes may also help with the issue.

During an attempt to compile the build using YYC output, a Compile Error was displayed:
Object: objScreen Event: Draw at line 10 : using uninitialised variable 'backScanlines'
This is actually related to a 'CRT' visual filter that was cut early into development. It could be seen in the 2014 demos of the game, but was removed since then, perhaps in response to negative feedback on the feature.
Rather than simply remove the remaining trace of this element, it would be preferable to bring the feature back as part of the final game, with constructive suggestions incorporated. This would include both visible scan lines and a 'phosphor glow' effect to create the illusion of a CRT television display. It may also include other, undefined display adjustments as necessary to create a visually pleasing experience.
No other alternatives have been considered at this time.
Additional context

Environment:
Steps To Reproduce
Expected Result
There are no visual or play issues present.
Observed Result
There is a blank power-up icon present in the stage.
Additional context
By default, blank power-up icons grant extra lives; because Special Stages are designed to have only one extra life icon at a time, this behavior is probably not the desired behavior.

Environment:
Steps To Reproduce
Expected Result
The enemy is frozen; all animations and behavior are paused until the condition wears off.
Observed Result
The enemy is frozen; animations are not paused, and the ice block shakes long before it's about to shatter.

An asset is any editable resource found in the resource tree of the project. This includes the following:
Because re-purposing of existing assets may result in used assets becoming unused, this ticket's completion status is expected to fluctuate.
Environment:
Steps To Reproduce
Expected Result
The player character leaves the screen; a time travel screen filter is displayed, transitioning to the alternate time period (past -> future, or future -> past.)
Observed Result
The time travel screen filter is not properly displayed; the shader which creates the warp effect is not active, resulting in a completely white screen transition.

Expected Result
The player character successfully navigates the loop.
Observed Result
The player character may not complete the loop successfully going in one direction, and will fall to the ground instead of running down the lower half of the loop.
Additional context
This issue is likely due to objLayerFlip; therefore, it should occur for any looping terrain structure that relies on objLayerFlip.

Environment:
Steps To Reproduce
Expected Result
The terrain collapses; there are no functional or graphical issues present as the terrain pieces fall.
Observed Result
The terrain collapses; the upper most layer of the terrain pieces have opaqueness where there should not be, resulting in the player standing noticeably higher than when the terrain was still 'stable' and ruining the illusion of the terrain crumbling away evenly.

Screenshots
Environment:

The enemy is frozen; animations are not paused, and depending on the timing, certain behaviors continue to function even while frozen.

Environment:
Steps To Reproduce
Expected Result
The camera stops at the end of the intermission area.
Observed Result
The camera stops at the beginning of the corridor from the mini-boss' arena.
Additional context
After defeating the mini-boss, the left camera boundary is moved ahead to prevent the player character from returning to the mini-boss' arena. This occurs again after navigating the short intermission area before the actual level begins and the Zone Title Card is shown, preventing the player character from re-entering the intermission section meant to bridge the boss fight with the 'actual stage'. After time traveling, this boundary change should be maintained, as the respective areas in both the Past and Future versions of the level are meant to be treated symmetrically. However, only the first change is kept, closing off the mini-boss' arena, and not the second change, which would close off the intermission area.
Screenshots
First boundary, after defeating the mini-boss (Future)
Second boundary, after the intermission area (Future;) this is where the level 'officially' begins

Sonic Time Twisted is a very large project. Compilation of the entire project from a clean cache can take up to 15 minutes when targeting Virtual Machine (VM) output, and over an hour targeting YoYo Compiler (YYC) output. (This is assuming a somewhat stable PC with a large amount of memory) Compilation time improves only slightly when reusing a fully loaded cache, but due to the way GameMaker Studio 2 handles asset changes, starting from a cleaned cache is sometimes unavoidable.
The most direct way to improve compilation time is to reduce the disk size occupied by assets in the project, so that packaging those assets during compilation takes less time to complete. This can mean:
These changes may have a small side effect of boosting game performance, since the assets will then take up less memory while running the game.
We may also conduct an investigation into how GameMaker Studio 2 decides when to re-compile the game's packages, and incorporate it into our Contribution Guide so contributors can work more effectively on the project.
Environment:
Steps To Reproduce
Expected Result
The player character re-enters the level at the position of the Special Stage Ring they entered from; the player character's previous shield is retained with no loss of functionality.
Observed Result
The player character re-enters the level at the position of the Special Stage Ring they entered from; the player character has no shield power-up.

An asset is any editable resource found in the resource tree of the project. The task required will depend on the asset type being modified.
Cropping is exclusive to Sprites and Tile Sets. It involves cutting out empty or unseen pixels and cells from the assets so they take less visible (and disk) space on texture pages. Reportedly, the Game Maker Asset Compiler (GMAC) crops textures when creating the .win package, so the time gained from pre-cropping may be negligible.
Compressing can mean using a data compression algorithm to encode a file in a format which removes unnecessary bits of data in order to reduce file size. This form of compression is most relevant for Sounds. GameMaker Studio 2 re-compresses audio to .ogg format if they're streamed, and .wav if they're not, even when they're already in those file formats. Consequently, changing the file format may not increase compilation time substantially; however, it may mean a significant reduction of on-disk space, which is important when cloning the repository and pulling asset changes.
Compressing can also mean re-creating assets in a different way that results in less data used. This is most relevant when it comes to GML code assets, such as Scripts, Shaders, Timelines, Objects and Rooms (ie. "Room Creation Code.") These code changes will be the largest source of time gain.
Re-purposing is similar to compressing where an existing asset is re-created to use less data. This is mainly referring to changing how Sprites are handled - whether they take up their own texture page, or have redundancies that can be effectively cut out through code changes, etc.
Paths, Fonts (unused) and Notes are not included in this enhancement.
Environment:
Steps To Reproduce
Expected Result
The graphical quality is consistent with the rest of the game.

The foreground tiles look blurry and stretched out compared to other levels; there are noticeable texture artifacts.
