Hahaha, right away you triggered my finish button I forgot to take out after testing the ending. Totally my bad, I'll be uploading a build without that soon :P
Thanks for playing, sorry you didn't find the attack button! (it's in the description on the game page but I should've put it in the game)
If you want to try again, I'm running this casual high score contest until November for a chance to be a unique enemy or friendly NPC in an update
