This game is pretty amazing and the soundtrack is absolute fire. Unbelievably good!
I was slightly weirded out by the RTP instead of seeing your own art style, but that's understandable being a Harold-centric game. My other slight, slight negative was that the gameplay in between battles is kind of on rails, but the writing was so good I mostly didn't care.
Fights: great.
Story: great.
Dialog/humor: great.
Did I mention the OST is ridiculous?
I'm definitely gonna play this again. Excellent work!!
EDIT: played through again and found several things I missed the first time. Great job gating secrets behind battle actions :D
Battle system is HARROWING on One Punch and I wish that the one or two skills that restored shield were removed or did something different on that mode, but that's so minor. It was super engaging to have to manage Aggro, PP, and set up damage against the enemy all in a delicate balancing act; you can't just stall indefinitely because they'll run you out of PP, but if you go too aggressive someone gets punched in the face. Draining enemy PP is a bit too meta, but having one slightly overpowered strat did not hinder my enjoyment at all.
