1. Yeah, you can pretty much grab onto the same ladder with no issue... that's because you don't fall while taking knockback on the fangame, but you do on the originals.
2. You mean like screen-size x1, x2, x3, etc? I'll take note of it.
3. The are checkpoints before the boss, but not mid-level, most likely going to add mid-level checkpoints.
4. I would need to check how to do it, but seems like a nice idea.
5. Just fixed it in dev build.
6. They take roughly the same time as in the original, but I'll take it into consideration.
7. Many people have reported similar issues, I managed to replicate the bug on the latest dev build, I'm working on it.
