Fun/Mechanics
In this puzzle game, you swap colors by jumping and you can only interact with platforms of the same color. I think this is a fun concept and I think having the switch mechanics be tied to jumping was a good idea. This forces the player to think about when and where they jump.
If you were to expand on this premise, I think you could add more mechanics that tie in with the color switch idea. Maybe like platforms that change colors when an enemy touches it or something, just as an example. More mechanics in addition to the enemies you have would add more variety to the game.
Theme
The color switch ties in to the dimension/duality theme very well and makes for a great platformer/puzzle game idea.
Aesthetics
The art has a simple two color Atari-like style which works well with the game’s mechanics. I also liked that you can customize the colors to your liking.
Music/Sound
The main theme you chose is catchy and fits the retro style of the game.
Overall
A good concept that ties in to the jam theme well. The game would benefit from more mechanics, but I think what you have so far is pretty solid. I want more!
