I really enjoyed this game! The inspirations are clear but the wide window and the dodge / roll / jump made it feel fresh. I also loved displaying your vertical speed at the top, it all worked together well to dare you to take risky, long jumps and the quick restart meant losing wasn't that punishing. I think the loop of big fun jump into progressively more careful jumps as you get a higher score and loss becomes more punishing is very effective. I would have loved a song - the sounds that you used really worked, but adding a soundtrack could have boosted it further.
