exchange 3 power for 5 hp, __ damage doing for __ attack or you can 5 power for a card. space to open your inventory. 1 for double damage (if have card), 2 for life steal (if have card) and 3 for refilp (if have card).
please enjoy. I'm not really good at coding so if your under 0 hp then skip your turn, please and thank you. update 1.0: released, sorry if the life steal card doesn't work.
