Nice submission!

There is a bug that, if I stand on the right side of the screen, the rocks spawn behind me.

Nice work! I had a bit of difficulty at the start – maybe reset the game if the player goes off screen?

The barebones of the character control were there, and being able to charge up jumps of different heights could be used for some interesting platforming. At the moment though there isn't a win or a lose state in the game, and I found that after dodging the first few rocks they stopped spawning.

Nice submission!
Some ideas for a post jam version:
1) Show the walked distance to give a sense of progression
2) Limit the jumps to keep Luna on screen
3) If it's too hard to detect when Luna is not longer able to stand and keep the game working, you could just put a reset button 
4) Maybe adding an overlay at the start with the controls?

The game seems to be a bit buggy and once Luna falls, she can never get back right up. But overall nice work!

Nice background. I like the music, but the kick is a bit too loud.

Initially I didn't know what to do and the character was pushed offscreen. 

The game doesn't seem to have any goal and there's not much challenge.

There doesn't really seem to be a death/lose state, the game just kinda.. keeps going. The jump being on the release of space is also really odd-feeling. The music is good, if a bit loud.

Nice graphics and background ! The Luna character is awesome !

Just walk forward and off the screen - boom all obstacles avoided XD

this is fun to play!
