Graviblox is a simplistic puzzle game that is based on different block types and the ability to switch gravity on and off.

Controls:
Arrow keys - Move
Space - Interact with the selected block
G - Toggle gravity
R - Restart level (if you're stuck)

Because of the limited time I wasn't able to create as many levels as I had originally planned to, but I didn't want to enter the jam either.
I failed miserably with my first game idea, on which I had been working for over 15 hours, so I had only half the time to come up with a new concept.
I hope you'll find it interesting and fun to play nonetheless.

On some computers, the library I used seems to have problems loading the sounds. There also may or may not be problems with text displaying. If that is the case, I apologize.

UPDATE: I just updloaded a bugfix, enabling you to restart the level if you're stuck. I hope that still fits the conditions.
