Haha Yes... A psychedelic freefall into an infinite abyss.
Stopping it changing at the last moment is a good shout. Will implement that. I'm adding extra visual cues to show which colour is the solid one, so hopefully that will help. And power ups and in the way to slow down the rate of change, reset the whole floor, or highlight the solid colour, etc.
I've also got different types of palettes for different levels of difficulty, one being a 'stand- out' palette which makes the floor colour really saturated, whilst the changing squares are pale, pastel colours.
Thanks for checking it out.
