Ring Demon was level 17 and it was really messed up. He was only 11% of the way through the level, and so far the level contained:
- A frame perfect jump at the start, on an orb that you had to hit late or u wouldn't make it out of the spikes, but if you hit it too late, a spike would appear and kill you
- orbs that vanished on you
- 3 consecutive frame perfect robot jumps
- flying the ship mode through an extremely narrow window of space with blue platforms all over it so you could accidently reverse your gravity and get killed
- fast waving through a confusing section of obstacles in random places
- flying the ship mode through a narrow and wavy area filled with yellow orbs (like what sakupen circles does), so that you have to time your flying so you don't click while you're on an orb or you'll die
- rapid maneuvering of the ball mode on one of the fastest game settings, also with several frame perfect moves
- dual mode jumping on orbs to get into a narrow window of space to fly the ship mode upside down through
- an extremely difficult wave section
- frame perfect jumping into a straight fly
- an area where you see absolutely nothing
And the funny thing is, he started working on a sequel called Ring Demon 2 that was even harder than all that within the first 2%
He also started a third one but that one made even him mad bc unlike the first two, which look menacing, the third one looked like a robtop level but had frame perfect jumps in it in the ball mode and the square mode. The third one doesn't even look like a hard level but it's really difficult
But he lost all of those levels unfortunately
