Really interesting concept. It feels good realizing the correct way to one shot the enemies, which overall makes sense because of the intelligent enemy design. I would add though that some enemies' faces or design make them feel pretty dumb and harmless (with those kind of silly faces).
Got a max score of 16 after playing for around 5 to 10 minutes.
The concept is pretty straightforward and catchy, making it easy to jump in immediately knowing what's going on and what i'm going to find.
Nice game!
