I don't know what you're talking about, every stage focuses on a different gimmick:
GPZ - first stage, easy light platforming over water
TWZ - conveyor belts, bouncing on goo, trying to get as far below lasers and so on
FHZ - Slippery Floors.
SLZ - Pushable gargoyles, water slides and so on.
MMZ - Horizontally moving platforms, dodging lazers
QCZ - Speedy stage with plenty of ramps and springs to get launched off.
MRZ - Crumbling platforms, quickly raising floors, and raising lava.
Do you think the special stages would be better if they were just "here's a room, now go collect spheres before time runs out" ? I am trying to make them as interesting as I can, I'm working on this alone so I'm sorry if this isn't dark souls level of difficulty or not as long as you wish, This is, after all, a fan made level pack, I think you have way too high expectations, I never promised super complicated intricate levels, just some fun short levels to blast through. Let's have some positive energy mkay?

Thanks, I'm definitely doing that next, I didn't know how to do it so it looked kind of weird finishing the last level and being taken to the original outro cutscene.
Indeed, I've added a couple of enemies that are tricky to avoid like jetty-sins and buzzers so hopefully the level will feel a bit less empty, and I'll also try to expand it with an additional section and see how I can make more use of the slippery ice after the exit.
