Pretty neat, just a few issues. I'd like some basic settings since starting in fullscreen means quite a bit of stuttering (for me, at least), and the music breaks frequently, you can fall out of the world in the second room, and I feel there should definitely be a tutorial prompt telling you to suck up water to make more goo. The game is also pretty sluggish whenever you're in first form, and even then the slime shooting mechanic makes you slowly reposition to line it up (I'd say it might be better for a game with a fixed camera where you can use the mouse/second stick to aim). That said, still a pretty fun game, movement is great (as always) after you get second form, and it's fun just to move around.
