The meow weapon is great! I found the song super catchy, and I really enjoyed playing through the level. And the cat ship is totally adorable.
I didn't manage to get to the end of the game though, as I kept dying to the boss. It is a bit of an HP sponge haha. One thing I'd change is the size of the hitbox - it seems to be a bit large; And the fact that touching the edge of the screen damaged you caught me by surprise. Otherwise super fun entry!!!
