GREAT concept, but unfortunately the controls feel awful and make it a bit annoying too play, because you can keep dying because of bad/inconsistent controls, at least that's what it felt like to me.
If jump was better responsive & not so penalizing for slight off timing (i.e. jumping off the ends), and the view box was bigger (makes it super hard to land accurately when you can't see what's below you). Really well done, but hope you can polish the controls a bit better, as that's the only thing taking away from it right now
