Hi! Thanks for trying the game. Yes, this absolutely needs more polish, I intend on fleshing it out much more after the jam ends, I already have some better, more up-to-date builds. The "4th dimension" being a color spectrum felt like a good way of communicating the 4th dimension to the average player, but I think the realization I needed to make from a UX perspective is that a "true" 4D platformer projected into 3D would feel awful (not knowing where platforms are, etc.) My game tried to toe the line by representing the 4th dimension as a color to communicate better, but I think the wonky controls and unclear visual feedback just made for a less-pleasant platforming experience. The feedback I've been getting has been highly valuable; as a thanks, I will try your game as well. Best wishes!
