no the rabbits aren't supposed to teleport you. I was adding some extra dialogue with a rabbit that would move around but didn't finish it yet. I'll disable them for the next builds until they are done.
Yes the red level is complete, as well as the two zones after it.
The arms are the same strength. It's not random of course, the behavior is entirely predictable just sensitive. As an example I will show the break the targets minigame here: https://x.com/ZanthousDev/status/1852729012126159198
If you're curious the specifics, a lot depends on the angle the arm is at relative to the ground when you start moving your arm fast (by inputting a high angle difference input). There is a dot on the arm that indicates when a joint is made with the ground as well, and these joints let you generally speaking jump further than if you are say sitting on the ground and slamming the arm into the ground with out it touching the ground beforehand. It's difficult to explain.
I've updated the hint for the climb regions to say "Grab - Hold L/R" and slightly increased the size of a platform in that area. Right now this is a bit of a pain point, figuring out how to balance this mechanic. It's apparently a quite steep learning curve to jump between these things. Back when I first implemented it it was a lot harder, and I've made many improvements over time to where it's easy for me but it's still difficult for me to predict how new players will handle it at this time.
I'm curious how much time you've put in at this point if you're willing to share, because I think your progress is decent all things considered. If you're playing on windows there is a replay file saved at %USERPROFILE%\AppData\LocalLow\Zankai\Sklime\Replays\The Depths, if you could upload that at some point I'll take a look at it and see where it might be good to make level adjustments
Also thanks for playing so much, and sorry it's a pretty frustrating game. It's been very difficult to get it to reach my expectations and those of players in some aspects. It's like an idea where you wonder why noone has ever done it until you try and do it yourself and slowly realize over the course of months
