Maybe just a warning somewhere for ppl who are a bit sensitive? It's hard for me to give any definitive advice since the colour stuff doesn't really affect me.

 I really love it as it is now--it's unique and the flashing visuals set it apart! The flashing serves as a great obstacle for the player since it's a bit disorienting--along with balancing ourselves and trying not to bump into the walls, it adds an additional layer of challenge and depth! The fact that you were able to tie the aesthetic and narrative into the mechanics of the game itself is very impressive!  Personally, I prefer flashier games like this! If you had a flashing lights/colours/epilepsy warning at the beginning, you could filter out the people who wouldn't be able to handle it while also exciting the people who are interested in that sort of thing!

I believe your aesthetic decisions are exactly why this game feels so unique and the challenge that the flashing colours presents to the player serves makes your game even more fun to play! It's a tricky balance--

Edit:  I hope I didn't overstep, I actually really love this game--I rated it all fives
