Neat game with good introductory levels to explore how the game works!
Currently, I feel like the later levels were mainly based on precise movement which was a bit annoying at times due to the movement of the cubes, where they don't instantly come to a halt. I feel like the hitbox of the cubes (or walls) is also a bit bigger than they appear!
But, I do think that with a couple of extra levels and changes, it could be a fun puzzle game!
(Also, I like Bloons too!)
