Good game. I like the color swapping theme, the game test your puzzle skills, your platforming skills and sometimes both, I don’t want to spoil but the reward for finding the buddies is worth it.
It’s a good idea to make all your levels open from the start, it’s better for testing during a game jam. Also you make sure the players understand before starting a level, nice.
The white color is a bit confusing though. i was never sure if it will remove the element or not. At the same time it’s a good, all included, color.
Also I would recommend adding a “color next” button on the ‘mouse 1’ for exemple or something else because during the platforming parts it might be difficult for some people to change color while moving.
You got a good base and different ways of using it already, keep developing them and it would be great
Thanks for the game, Good luck
