Yeah, a lot of people complained about the difficulty curve. Normally I would have spent more time on level design, but it was my first jam and I still had a lot of new things to learn so I hadn't that much time for smoothing the curve.
Anyways, glad you enjoyed Johnny Split and thanks for playing!
Also I'm planning to work on a full release of the game with adjusted difficulty curve ;))) Feel free to follow me, so you won't miss a devlog!
