Hey, this is a fun concept! I think some of the colors should've been different, as they were sometimes hard to see or hurt my eyes on the background (for example, the dark blue I had to squint to see). The buttons on the main menu and how to play screens were a little small and I would've liked them to be a bit bigger. Also, the "how to play" screen was filled mostly with text and information that I looked at once, knew I wouldn't remember, and decided I'd just figure it out as I played.
In the actual game, I think the shooting elements and dodging enemies was really fun. Changing shapes and shooting types added variety for different types of play. I didn't like the one with no shooting and no moving, as I thought doing nothing was kind of boring. But other than that, I enjoyed the rest of the experience. Well done :)
