Cool idea to use health as ammunition and the constant search for health packs keeps you on the move!

I can clearly see that the enemies are interacting with each other somehow, I just can't tell how. What exactly happens when they turn colorful? You also have some mechanical interactions (health - shooting) and (movement - shooting). I just don't get those 100% either and they make the controls feel a little unresponsive at times. :D

Visual effects are very satisfying. I'd like to see a bit of a texture in the background so you can tell how quickly you're moving and there should also be an indication of where the level ends. Invisible walls feel a little unfair.

Overall a pretty great game! Thanks for participating.

Great game! It's really satisfying. There are however a few things I'd like to mention.

First, make the walls visible and also let the enemies collide with them. Sometimes I wondered why I can't go right even though there are enemies. Also, warn the player if he is low health. It happened to me a lot of times that I was shooting and suddenly the death count down was seen. Make a warning noise if the player has low health and tint the healthbar red.

Also, please add a score counter so the player wants to improve more and more if he died.

Other than that, it's really a great game and I just couldn't stop playing because it was SOOO satisfying!

Make walls visible! Other than that, the game is really cool and fun to play :)
