Thank you :) You are supposed to tap in rhythm with the music/color changing tiles (web version has a strong delay on my tests) Maybe that’s why you had missed inputs?
The enemey’attacks target random cells, so you have a chance to get away with brute spam, but you are supposed to try and evade its attacks (orange cells before the beat)
I planned on having multiple levels without healing in between which would render brute spamming way less of a good solution, coming soon tm
