This game is a very creative puzzle platformer with such a nice level design. I loved it. At the end, when I got to the challenge levels I was like "wow, there's more?". It's impressive how such a mechanic could create so many interesting interactions. The double-punch thing was something I never even thought of trying before the challenge levels. I almost felt the urge to go back to the previous levels and try to S-Rank them all but I gotta play the other entries haha. I understand where people are coming from when they speak of difficulty but I really dig this kind of challenge.
Great job with this one!
