I've reached wave 15 at best in default difficulty so far.
I really like the bullet patterns of the enemies in this game, they're nice, you're still not wanting to trigger those, it'll often mean losing some health. The music is cool and I like the changing look of the protagonist when he is walking. The game works, I am not sure investing into the character's weapon is a viable bet, which is fine, just buy turrets and navigate through enemies, it's fun that way.
Tha game is fun, thanks for sharing.
