underrun's Issues

Why assign Math and document to local vars?

Not an issue as much as a question...

Here you are assigning Math and document to _math and _document respectively, why is that?

Thanks.

Scroll is active during the game

I love games like that and as a developer, I'd like to make you my congrats on your idea 🎉

I want to warn you that the scroll is active and could be annoying to the user during the game.
I attach a gif to demonstrate what happens.

Browser:
Google Chrome for Mac
Version 69.0.3497.81

I never make a video game and if you need some help I can help you with it 👍

Unusable in mobile devices

I tried playing on my Xiaomi Redmi 4x using the latest chrome browser, but there are no controls to move the player or shoot. Also the screen doesn't expand well.

How is the pulsing light effect created?

Hi,
great game, I learned a lot about webgl from your code, thanks!
I can't seem to figure out what is causing the flickering / pulsing effect of the light around the player, and the blue glowing walls, is it in the shader? Cheers

type error in Chrome

Great article! I get this when attempting to play the game:

Uncaught TypeError: Failed to set the 'buffer' property on 'AudioBufferSourceNode': The provided value is not of type 'AudioBuffer'.

game is too hard

any tips on how to avoid bugs ? :)

Please add a software license

I'd like to play around with this source code, but technically until you attach a license beyond the Github default I can't.
