You have a new and exciting take on traditional puzzle platformers here. It took a little for me to get used to it, but I think the idea is good. The execution could be a little tighter though. I found myself wishing I could adjust my trajectory mid-jump, but since I couldn't do that I focused on falling at the right moments. It was still pretty difficult.
The graphics are simple and easy to understand though, and the bits of dialogue, instructions, and tips helped to keep me focused. The music fit the aesthetic perfectly as well.
Overall, a bit difficult, but not bad!
