Interesting game. The difficulty spikes a little abruptly which is fine and maybe even good for this type of jam. There's definitely strong rage-gameplay here lol. I think there are some things that could be tightened up (most egregious: wall-grip animation is way too slow, causes huge readability issues as I cannot be sure whether I'm on or off the wall a lot of the time.
ah yeah the wall grip animation could definitely use some tuning. As for difficulty, we would have liked to smoothen out the difficulty curve, but we wanted to give experienced platformer players a challenge and didn't have enough time to create more levels. We will definitely add more levels in the future
