So, I will say the platforming itself (jumping, dash, move speed, etc) feels amazing, and the level design of the pack is great.
My main issue is the color switching often becomes extremely confusing for a beginner. There have been multiple times where I would be at the top of a section and fall back quite a bit because I forget which key is which color.
Another small issue is there should be a camera zoom setting, as on my 1920x1080 monitor the game is extremely small

Onto my recommendations, I would start with 2 colors, teach the player those, and then after the player becomes familiar with those, incorporate the third color. I would also recommend allowing keys to be rebound, as enter is a far reach to be able to properly recenter mid jump in order to change colors.
Overall the game is great! Good work so far, I hope to see more good things come of this as you have a really good base.
