Really interesting movement mechanichs, but I think you should point the player in last direction he moved, like if I moved left or down, he will face up as soon as I release the space key.It's kinda bad that the game isn't finished, but hey that's what game jams are for (experimentation and learning new things) :)

The main mechanic is quite interesting. But as you said, the game is far from being finished. Good job anyway

Cool idea, I think you can expand it after the jam is over, good job!

Nice mechanic. It's sad that you weren't able to finish your game, but it has potential for the future, maybe? Also, it is cool that you still uploaded your game, because game jams are about trying and doing something, everyone has different skill sets, experience, different amount of time to work on a project, so it's completely fine to have a not finished game, at the end of the jam. Keep it up, and  I think one day you will make awesome games!
