I like it! I loved the art style as I am always seeming to for your games, though this one was a lot more muted than some of your other games I played. Which isn't a problem, it's just a different style.
There are some issues with the difficulty curve for sure, and I didn't feel like the game really picked up until the real-time projectiles were introduced, which were great, but for a game jam game this is definitely a good game :)
