Wow! Looking at games on the jam submitted list, I immediately wanted to play your game because of its attractive cover. I'm new to the gamedev myself, but I think you did a very cool job for your first game. I liked the physical feel of the rocket and the good level-design, the levels were interesting to go through, there is a Challenge in it, but they are not too complicated. And it's beautiful in colour and illumination). Good luck with your future game creation!
