Your game's lack of an X button made me flip out. Fun game though.

The game is solid technically, but I'm not sure how it fits the theme "Enemies as Weapons".

One more comment: I think it might be more useful to shoot in the direction opposite to the one you just moved in. That would let you shoot while running away.

Basically the theme is that you need you use your enemies to reload your hearth (and shoot more hearths) since, idk if you realized andi forgot to mention, totating and firing takes energy away.

Gotcha.

I often got in the walls when rotating the world.
I didn't get the hang of where you were shooting.
Also shooting didn't seem to drain any energy.
I like the concept though.

I liked the online highscores.

I didn't quite understand the game though, or what it had to do with the theme. I guess I was kinda shooting enemies with hearts, which made me lose my own life. By the way, I kept expecting the A/D keys to rotate the world the other way around, but maybe that's just me.

Crashed accessing the high scores as well as got stuck in the wall at one point. Being able to know my fire direction before I fired would have been a great boon, especially since firing weakened me :)

I really couldn't figure out what to do even after a couple of playthroughs. Really a shame because I liked the look of the game and the concept of ammo and health as the depleting heart. I just couldn't seem to control it very well or figure out how to collect more heart power.

I got stuck in the walls when I rotated, and more or less got really confused when I did.

Interesting concept. Aside of getting stuck on walls sometimes it's a solid game. :)
