A combination of GIRP and Jump King, the bane of browser-based gamers everywhere! The ramp-up on the power bar was too quick for me to get the hang of, but there's some nice juice with the screen shake and sound effects that made it satisfying to try anyway. I also had some trouble expecting (and failing) to grab a wall when only a small portion of the sprite was covering it; I'm not sure if that's a reflex issue or a hitbox that could be refined. Lastly, I think bouncing off the side walls would be a welcome tweak, as it would allow you a chance to recover from some missed jumps rather than falling all the way to the bottom. As a fun diversion, I had a good time. And the cutscene I imagined was a breathtaking experience :)
