I like the idea, there's some rough edges but I figured out how to manage combat fairly well. I think player feedback is important, like when an appendage is destroyed maybe the button for it is disabled and greyed out? The game design is very simplistic and just ends up being "Choose the bigger number against the enemy's smaller number" most of the time, which isn't inherently bad but I think you might have some more depth in mind. At least you made something playable in time to submit, that takes a lot.
