Project B

Giving 30 points.

Very interesting concept of the game. Tough to play from some point, but perhaps this is not a disadvantage. I would add some guidance at the beginning to make the player get used to mechanics. Positive impression overall. I did not see any cons.  

Really love the idea of switching colors. Would maybe recommend lowering the difficulty a bit, or be more forgiving. Maybe making the jumps less absolute precision needed would be nice, as it feels too robust. Also adding the option to see whole level clearly, as it's hard to remember both parts, especially closer to the end, which it makes it more frustrating. Other than that, I absolutely love the main idea and the wall jump, that is a really nice addition.  

Perfect game, the game is quite tough, but I wouldn't change that, because it's more challenging and it forces the player to repeat the levels until he completes them. Maybe in case of repeated failure, it would be advisable to provide help or instructional icons on how to overcome the level. Overall, the game doesn't have any issues or bugs, it's really great.

Fun to play. Love the idea.
The hints about the mechanics could be handled more clearly.
Checkpoints are spaced well.
