This as an interesting take in the 'pool' mechanic!! Loved how challenging the levels get! The spritework is also lovely!! I got stuck in one of the spike levels, but I enjoyed a lot how the game is presented!
If I had to say anything it would be to add an indication for how much green I should get for each level , in order to open the door... not that would make a difference for my lack of skills, hahaha!
Solid entry! great job for the team!
