So, it seems that jumping while in Redhot Ride act 2's lava after a fire dash is quite a challenge. Also, I found a weird item box in Horizon Heights act 1 that gave me a blue shield, which went yellow, then red, then disappeared and destroyed all the on-screen enemies. What in the universe is that supposed to be?
EDIT: I can record the game fine, but do note that I get slowdown in some levels.
