I think the falling effect and the gameplay is really pleasant, especially with the music and art you went with! I think the gif and character selection features are really cool and I don't think the lack of control is necessarily a problem, but the thing that stands out about it is being able to see a character falling in a fun way, and make gifs and share them! I could see someone playing this on a train when they have some downtime! I think if going further with this, a shorter average length for each run and some more elements to elements to make the way you fall more dynamic would add a lot (e.g. bombs that make you spiral or have unique explosion effects or do other wacky things), as well as having some things you can control at the start (e.g. how fast you run, when you jump, initial spin, some characters having different physics properties), but I think the surprise of what's going to happen is a cool idea that worked for me!
