Thank you for the honest feedback! Some greater indicator of damage would've nice, I do agree, but I sort of ran out of time to implement that over all of the other bits of polish. Sort of regretting that now but what's done is done! I might come back and add a little bit more instruction to clarify certain bits of confusion you had once the jam is over, thank you for bringing that to my attention.
And a quick side note: you *can* just stay at the pond and heal infinitely, but you'll be too weak to kill any enemies if you do that. Remember, the game is about getting a good score, and that means using the pond as little as you can in order to keep your stats! You'll also eventually die since there will be so many enemies you won't be able to press heal quick enough.
