Really nice game. Good for you that you got to 23 votes ;)
I really enjoyed playing it, but it has some points you should improve. But before, I would have rated it much the same as your final score, with the theme getting a lower rating. It was not really present in my opinion but the mechanic was fun.
Now to the points that need improvements
- I found two typos "hapenning" should be "happening" and "i'm must" should be "i must". You used "not bad" three times very close after another. No other typos found.
- I like snappy movement, but your speed is maybe a little too fast. Consider tuning it down a little. Not much, just a little ;)
- I'm not sure if this would make your game too easy for some parts, but I really enjoy adjustable jump heights based on how long you hold the jump button. Maybe you can experiment with that feature a little bit. You could add low jump passages with spikes above and below. Similar to what we did in our game, but without the dash :D
- Playing as the white player can get a little tricky when you are jumping in front of the white background. Some jumps where a little harder to perform. For example, the first jump as white player in your last screenshot. I like the idea of turning to white, so I don't know how to solve this issue best...
- Improve gamepad/controller support. I had to change to playing with my PS4 controller in the last chapter. It helped finishing it because I don't like playing for a long time with the arrow keys. The jump button on PS4 was on the triangle button and for some reason Pause was on the cross button (Yeah cross, not "X", because that's what Playstation wants us to call it :D).

Nothing of the points above were game breaking, just general improvements. Going to follow you because I want to see the final/next version of the game ;)
