This game is full of fun and difficulty. Difficulty first because this game is hard as nails. I'm not sure if it's just that a lot of people dont play online, but at this current point, only two people have made it past 2-2 (one of them being me), and one person past 2-3, since I haven't gotten that far, and I'm on the easiest difficulty. But you will be spending a LOT of time trying to beat this. The color changing mechanic makes this tough as nails, and all of the bullet-hell elements in it makes it equally insanely difficult. Every end level boss will beat you to a pulp, and you'l enjoy every second.

The game is definitely a fun one. Very lighthearted, and loves to have fun. Its meant to be fun, and doesn't beat you up for losing. It's got a lot of little fun bits and you can unlock fun little accessories, so you can have a good time, so long as you don't ragequit first.
