Hey, cool game! I liked the idea of having limited lives to clear the level - it helps you stand out from the crowd of kill-yourself-to-progress-platformers (I haven't seen another one with that idea yet.) I felt the controls could have been a little tighter (e.g. coyote time, or taking a tiny bit of time to accelerate/decelerate. Maybe also could use arrow keys for movement so it's more natural to use both hands?) But overall a good game, all the more impressive for this being your first jam - good job!
