the control is great, but I confuse about the objective of this game.

Honestly, the game seemed fine once I got the hang of the controls. I like that you made all of your own graphics, conceptually speaking I think this had promise. I know you don't plan on continuing but this was still a great effort, the controls were intuitively but the camera was unable to keep up to the speed of the craft I was controlling. 
Nice effort!

It's unfortunately too buggy and broken,  but it seems promising. I would like to play once you update after the jam.

(btw you can edit the description of your game, you just can't upload a new version right now),

Fun and crazy controls, i wonder how it would look in VR. Unfortunately i didn't know what to do and got stuck real fast, but just flying this ship is fun!

Very weird physics and controls but the “stick to a surface” mechanic is a promising as a start. Unfortunately there are no instructions and I quickly got stuck in geometry.
