I'm glad to hear you enjoyed the controls, the character controller was probably the one thing I spent the most time on so it's nice to see that work paying off lol. Difficulty is definitely something I'll be looking at with the post jam version as that seems to be pretty common feedback, and while I wanted it to be hard I probably should've had someone playtest it to make sure it wasn't TOO hard. I definitely appreciate your feedback, thanks again for the kind words!
I think I spent most of the time with getting the character feel good in my game. You spend so much time with the protagonist, so if it feels bad, you suffer from it all game long, hehe. Also I like adding small particle effects and stuff to give geed feedback on the controls.
I also have a bridge where you must dash :-)
My game was probably on the too ez side of the scale though.
