Yeah, its hard to account for accessibility when you are under a time crunch and neither your developer or artist struggles with much color blindness or motion sickness. That would probably be the second thing I work on should I turn this into a full fledged game, the first of course getting the game's grammar and ratings systems from "Good enough for a game Jam" to "Good".
The game actually does keep track of a total high score and that is how it decides what ending you get. Unfortunately that is in the background hidden from the player, may change that later.
