When it is your turn, Blocky will walk up to the opponent and ready a punch. Press Z with the right timing to deal more damage. Press X after that and throw a second punch to deal even more damage. Try, please. It shouldn't be that hard.
This is a school project that kinda got rushed last minute due to me having a whole bunch of homework this night. Thankfully I did make a functioning game, though it's debatably worse than most of my other games, especially since I put in so little time. (If you counted all of my work on this game it would probably be 7 ish hours, if you exclude all of the spritework, probably just 1 or 2 hours) I will make a proper demo eventually and I'll probably leave it at that, but who knows! Maybe I'll make a real game of this where I make money!
