I like the art style of this game but that's most of what I liked about it. Couldn't get the gamepad to work (could be an issue on my end, but it's worked with most games that have the option) and the gameplay itself was annoying. It didn't feel like I beat the game by being good at it, it felt like I just bumbled my way through everything because it was almost impossible to lose. Despite that, the boss was just frustrating because it was impossible to get away from her in the second stage of the battle so every few seconds you're sitting through the color bar again.
I realize this is an early build, if you fix the level and the boss fight to be challenging instead of frustrating it would be a lot more enjoyable to play.
