Good thing I picked the easy door with double jump and floating gravity.
But really compared to last time I played it something seems better, idk which version I tried last time but controls do feel more snappier and mistakes feel like your own which I do like, difficulty also spikes really fast which I somewhat get but it feels like there's no relaxing period unless you stop playing.
I think with color balance maybe use blue color on your diamond grid for background tiles and keep pink for bricks/whatever foreground and make switches more readable somehow. I don't think you need to change much, especially main character which I don't remember if it had white outline with shadow last time I played but it works, biggest issue is pink on pink background imo.
