Hello!
Firstly, I absolutely love the pixel art, it is super cute. I also really like the design of this game. It took me a second to understand the turns mechanic but on my third run I didn't have to worry about health, ammo or turns as I was so stacked.
My run had to end midway though, I tried using my "teleport 3 steps" power directly on the stairs to avoid the enemies in between but my game froze and was slowing down my browser somehow. I am sad I wasn't able to reach the end but otherwise I do really like it!
