I've been going for this level for a while and intend to beat it pretty soon (I have 70%, 84%, 86%, and 90%). This level will test practically every skillset, and I would say it's notably harder than Conical Depression (I'm making that comparison because that's my current hardest)

The level starts with a long cube maze, which may put some people off, but that's alright. It gets very consistent and you end up passing it nearly every time. Next is the ship with a bunch of cube portals. You must avoid most of them, but the transition out if it is to take one of the cube portals. I find that transition a very clever way to add more memory elements to the level.

The first coin is in this part, and MAN is it hard to get a run past it. You have to just barely graze the coin's hitbox so you can still take the right path.

The level chills down a bit after the ship, but picks back up at what is probably the main attraction gameplay-wise: the 2 player dual wave.

You must hit 2 triggers, which will separate your dual into a big wave and small wave of same gravity. You must control both waves at once. There's even a coin in this part.

Once you pass it, you come to the final part of the level, and I would consider it the hardest. Not only do you have to learn all the patterns, but executing it is very difficult, especially 92-100.

I really like shmigels levels and their gameplay. They are very learny, but they're fun learnly and can be satisfying to pull off.

The reference to lunarmaze is neat
