Thanks for playing!
I struggled a lot with making the game fun... initially, it was completely trial and error and the safe zones which show you where you can switch without failing were added at the last minute.
I also considered a shader that gives the blocks a little opacity and white so they do not disappear and so you can better understand the level. However, since this was against the rules, I simply deleted faces to make you "look through" and rotated the camera a little faster so the hack was not completely visible.
I will maybe reiterate the game and use some of the feedback. thanks a lot for playing!
