Hey, after playing through this a few times and learning what to do, it's actually pretty alright. Once I know what to do and how to do it, it's a pretty exhilarating ride.
There are a few issues though.
1. It is not telegraphed whatsoever that you have to HOLD JUMP while doing Spark's air twirl jump-boost maneuver, not doing so gimps your jump no matter how long you hold spin for.
2. You HAVE to stop at that final checkpoint. There's no way around it, if you don't, you die, but it's all too easy to miss it, fly over it, and then fall into a pit.
3. Those Bio Satellite-esque lasers go too fast and too close to the entrance, it's all too easy to completely lose your flow just because you got an unlucky laser cucking you out of your dash mode right at the entrance. Other than that it's a fun obstacle to avoid, though. You should definitely play Bio Satellite from Kimokawaiii to see a way to make that same obstacle have a more fair entrance to that sort of obstacle, as doing something like that will make this a lot less frustrating to play.
4. What even is this place? None of these structures have any sense of believable structure or any context as too why its obstacles or setpieces are there. It looks very disjointed.
Overall though, I've gotten my time for all 4 laps down to approximately 3 1/2 minutes, which is good. It's fun once you learn what to do, although that definitely took longer than it should've @_@. It's a very unique playstyle though, and I think seeing a more polished map like this would be great! Hell, you could probably update this one over time and make it more memorable and fair as well.
1. To be honest I didn't even know it made *that* much of a difference; that's just how I've always done it. I've addressed this on my latest update post, though it's entirely forgivable that you didn't read it because I hadn't actually submitted it yet when you left the review!
2. I actually used a Star Post Activator sector to (ideally) prevent that from being an issue, so I'd consider that a bug. I've never experienced that behavior before, so I'd appreciate a demo or GIF of you going through it without it being counted, so I can investigate further.
3. I'll take a look at that level; thank you.
4. It's supposed to be some kind of giant computer in an abstract environment, but I agree that some of the setpieces may seem out of place. I might improve that if I find a good way to, but I don't think it's a terribly major issue. Do you?
