Cool idea! I included it in my 10th Creative Games Jam compilation video series, if you’d like to take a look. :)

Thank you very much.  I'm glad you were able to play it.  

The energy mechanic is quite clumsy.  Ideally I'd like to implement an altitude speed indicator that displays how fast the player is rising or falling.  The current energy bar isn't very accurate or useful.

It seemed like you had very little control over the game.  Even if my energy went lower I didn't start descending, so no matter my actions I would usually go over the moon.  I really liked the artwork.
