This game is.... OK. The idea of a time attack maze game is a fun one, but this game doesn't have more than two mazes and/or the available mazes aren't large enough for it to remain enjoyable.
Some aesthetic criticism: The textures are missing normal maps. Everything looks like painted plastic due to there being no normal maps.

To new people: WASD doesn't work. Arrow keys do, but only if you allow the app to use the keyboard in the security prompt when you full screen it (in Firefox).

ah, well, let's start with pros. Nice concept, 3D, not laggy, simple controls. Now cons. Music is slightly annoying, barely difficult, only 2 wall textures, very slidy, not able to use WASD for movement. I could name a few more but I'm lazy. Overall it's okay but it could use a lot of work.

WASD does not fucking work. Needs a reset button. Music gets annoying after a while. Would be a decent maze game if it weren't for those.

Your concept for a maze game is nice, I like how it looks, but you should give us instructions before the game starts, I didn't know if i had to use WASD keys, arrow keys or the mouse to move, and a bit more of variety will be appreciated.

I hope to see the final result! Good luck!

Looks nice but there are only two mazes? Needs far more, please add music/sfx as well.
