Could you go into detail with the issues you had? Constructive feedback is great, I'd just need more info to be able to improve on them.
The movement felt quite slippery and slow to accelerate at the same time. A lot of the platforming jumps felt too tight as well. I often felt like it must not be the intended solution.
I also got myself into a soft lock I believe. I somehow found my way into a room with an upgrade that seemed to say I could relocate myself ? However, I couldn't figure out what the command for it was and trying to leave manually was impossible.
Regarding your issues with the difficult jumps, a big part of the issue is most likely the level design not pushing the player enough into doing jumps in a sensible way, which can lead to a lot of "cheesing" them in ways that are messier and harder. We'll look into addressing that for future versions.
The powerup's main purpose is to unlock the stomp ability, which is harder than intended due to a bug where the jellie enemies' hitbox is higher than the sprite. The powerup also unlocks the goto command which is revealed elsewhere so if you are stuck, the command 'goto wakeUp' will take the player to the first room. The hitbox issue is fixed and will be in the post jam update.
