I just found many glitches in your game, especially in Challenge:
- Starting a challenge by going through the door to get the timer started, then hitting escape -> Menu -> Play challenge, doesn’t reset the timer. This glitch is demonstrated by my #5 placement in the leaderboards: as soon as I crossed the door, I started the challenge again after going to the Menu.
- After repeating #1 many times, the timer simply refused to start and was stuck at 0:0, even after I completed the challenge and got to the end. Here’s a screencap of it, which also shows some visual glitches with the far wall too.
- Story mode, after the above glitches, started in the middle of space, not in the first room. I just flew around in the stars :S
- Footsteps aren’t stopped when going in menu
Really good game though!
