Hello Jellybeans,
Firstly, like @BillyMan said below, the game window is far too small and it makes it really hard to see what's going on. Despite this, I really liked the artwork, animations, and music, they look really nice and the music fitted it all great too. It's a fun game, but it's missing some sound effects and direction, I still don't know what I'm supposed to do in the game, I end up just shooting endless waves of enemies, with no score or indication if that's what I'm supposed to do. This is a great start, but it just feels a bit unfinished. If you had more time, I'm sure this would have turned out to be something great, but as of now, this seems like an unfinished game.
