This is in a super crude state right now, I know... but...
It is boring. I have already played this before, but it was in 2D instead of 3D. Just fly to the box and then land. I wonder what else are you going to give it? Would love to see this developed into something interesting.
The music is fine, but the sound effects forced me to play this game muted.
I encountered two bugs: Game telling me that I have won, even tho I crashed into bambilions of pieces, and game music suddenly stoping in the middle of a beat. (But you probably already know this and you just left it in, which I guess is understandable, since this is an early build.)
Hey, good luck with it. Hopefully you are not stoping in this stage of development. Otherwise I would not have given you 4 stars.
