I already thought it was super well polished for 48 hours, and then notice you did the art and audio as well?! The challenge seems impossible up front, but after some experimentation I eventually learned the physics enough to beat hard mode, so I thought the difficulty was tuned perfectly (though I've played a lot of KSP). Only suggestions would be a way to reposition the camera to make it easier to judge depth, and maybe a longer death time-out since one time I did hit the door during the game over screen. Overall amazing game, though. Well done!
