Cool idea. Maybe this is personal preference, but I felt like once I jumped, my landing position was almost fixed. A little more in air control would make it (for me) a bit more enjoyable and a bit less frustrating.
It's definitely a bit momentum-based, I had done this on purpose but in hindsight I don't think it was a good idea for me to do, especially for a platformer. I'll be uploading a version with more aerial control once the jam is over!
