Thanks for the feedback! We had some difficulty making a satisfying character controller, and changing it after the level design is done risks making the game unbeatable.
Since I had some time today, I made an alternative version with different movement controls (I also fixed some bugs and softlocks) that you can find here if you want to play the game more: https://github.com/StupidHobbit/GMTK2024/releases/tag/leroymilo_cut_v1
Please make sure you rate the game published on the itch.io page, because the version linked in this message was finished after the Jam end.
