Super cute, simple game. I like the idea that you have to balance your weapon around either being small and fast or large and slow. I also like the idea that you can throw your weapon.
Possible improvements:
Sometimes it's hard to find the enemies. An indicator would be really useful.
The dash is really small right now; maybe increase the distance a bit.
Besides that, I like the idea and would love to see where you are taking it from here. Good job!
