Wow! I liked so many things about this game!
Aesthetically, I'm an absolute fan! The weapon and color mechanics are perfectly executed. The bosses are all very different and interesting. Even the menu is really good, and it even rotates!!! In short, well done, this game is a little nugget!
What's more, in both our games, we have an unbearable bubble fish as a boss, and I had at least as much trouble with yours as I did with mine. It made me laugh xD
Bravo again!
