First off, not a dev!
This looks like it could be a fun runner, but there seems to be no way to jump outta the way of obstacles, and I seem to die randomly. Also, after hitting "retry" a couple times, the game had trouble spawning the character, and nearly dropped them through the environment at least once, before it fixed the character's positioning, so, good on ya for putting in a corrective measure, but the placing still needs work.
