Thank you very much! In retrospect, I probably should have made the shop more visible lol.
Glad you liked the locational damage system!
There is a primitive multiplayer game that I worked on that uses the same-ish combat system here: https://boomba-zoomba.herokuapp.com/
Glad you liked the AI - worked really hard on it.
Maybe I'll make it into an io game at some point. Need enough players first tho. Maybe if this game gets enough attention.
