Thanks for the hint with the cemetery sphere!
It's definitely a difficult control scheme to get used to. The movement acceleration and tendency to bounce off of vertical surfaces makes several of the jumps extremely difficult. The red sphere on the shelf (desert/canyon) took me 20+ tries to get inside of the cave to complete it. Learning the right time to scale yourself down during a jump for maximum control is extremely difficult for me for some reason.
I do have a few bugs to report, though.
- If you go inside of any other sphere, whether you complete it or not, then go in the desert/canyon sphere, the game will lag severely going from a smooth 60fps down to just 4-5fps. The longer the game runs, the worse it gets, especially if you're trying to record your gameplay. If you go to the desert/canyon sphere first, the lag doesn't happen.
- Changing your resolution, fullscreen, or quality options have a chance of causing textures to be badly mapped.
