This was cool! The music and the premise was fun. I always find these kind of games kinda difficult to balance right because the higher dmg is always just more fun. I dont know if theres a fun benefit to doing the more defensive version or the one where you turn into a rock. Ultimately you are still playing the game the same way but one way drags it out a lot and the other way makes it more fun which dont feel much like option, maybe if the different lvls had different powers to use? Either way, I think overall the core gameplay is solid and its a fun experience with the red version :)
edit: also, the sounds and music are amazing for sure
