I thought the premise was neat and the way you shoot your own hp is very fitting. My main critique was that the following enemies kinda end up clumping so you just end up looping them in a circle unti theyre all on top of each other, they need a little bit more complex movement in my opinion. Also the music and sounds did get a little grating after a while, maybe the sound effects were a bit too loud?

cool use of the theme

The gameplay loop is pretty fun, and the way the enemies and such are set up leave it open to a few different playstyles.  Personally i enjoyed trying to make the enemies kill each other.  Though it felt a little imprecise as to how much health was lost per charge shot level.  As for some finer feedback tho:

• Movement was pretty snappy, no issues there.  There were a couple bugs but that's not really feedback.  Mostly just wanted to say it's a well done movement system and it was enjoyable to mess around with.
• As I said above the "charge shot" doesn't really seem clear in how much health you lose depending on the charge, which was a bit annoying.  Having to guess and everything.  It seemed relatively close to the health actually lost in the health bar, but just enough off to be a bit weird.
• The tutorial being part of the gameplay was pretty nice and seamless.  Which was a nice change of pace from either no tutorial or bare minimum tutorials.
• Doors.  The doors were weird, at least in my opinion and a couple people I know, since they were protruding from the wall which was counterintuitive to most doors in games like these where they are gaps in the wall.  So I had a lot of times where I ran into the wall thinking it was the door just from experience.  So many switching that a bit?  Thickening up the walls, or zooming out the camera slightly, and then shrinking the "door" blocks could help..?

Overall a nice simple concept with a fun core game loop and a bit of variety thrown in.  Though there was one game breaking bug that I seemed to keep running into where I would "teleport" outside of the room, generally it seemed to be teleporting me to the same location, which was above the starting room, and to the left of the first room with "turrets".  I'm not sure what was going on, but it definitely got a bit annoying.

i really liked this game, it's very addictive and fast paced! the theme is well merged into the game, and the controls are great, the need to think before shooting makes the game a fun challenge, i can't imagine how awesome this game would be with more time put on it, you have a great initial project to start

Nice game! I always seem to find myself getting addicted to these dungeon-type shooter games. The controls felt great. It's a simple but fun game!

I really enjoyed this game, up there with the best of the jam! I really liked the dynamic percussive music for when enemies are around, and the recoil from each shot gave a lot of power to shooting. The concept of life being ammo fits really well, and I like how it carries into the next level.  The boss had a bit too much hp in my opinion, but the second phase was really action-packed! The game could do with a bit more content as well. Overall really great work!

Great concept. Art and music could be better. Overall interesting game.

This game should be win in "Theme" category. Very simple and cool concept.

A very great concept, there were a few bugs though but its understandable since its a jam game, would like to see this concept expanded further

Nice game!
