That's sad, that's the second game I test that couldn't make it to the jam and was worth the try because quite innovative and tryed to actually have the rotation at the center of the gameplay!
The gameplay is better at the second level, the first one there's not so much to do (and I can't aim too far from the base I always miss ^^', I guess, that's close to the fact, don't go too far away of your territory ^^).
But it gets really hard and I died 2 times there :/.
The music/feeling of the game work with the assets!
