Love how the music slows down as well as the whole game and thus gets calmer while on the left side... Although it still is pretty calm on the right side, which might be a problem? I personally like the calm music but it might not fit so well with the shooter gameplay...
Also its fun how on the left side you can retain your speed by bouncing off walls like the DVD screensaver. I kinda wish at gave you more of a boost though to make it even more satisfying.
Also the gameplay got a bit repetitive after a while. I'm not sure if this is even reasonable criticism for jam games because you can only pack so much content into the game in a short amount of time.
The difficulty curve seemed a bit wonky. I didn't take any damage until wave 9 and then I got ganged up on and died.
Very unique game! Congrats on submitting!
