I like the idea and gameplay. I got a little bit of Will You Snail vibes from the art direction!
The end boss and the many soldiers level points towards a bullet hell, manic style game, and those were my favorite parts.
Glad you liked the game! Honestly, I don't know Will You Snail, but it's cool that you picked up on a similarity like that.Also, my favorite part was designing those bullet hell-ish sections you mentioned :P !!
