Excellent work! Original and fun action puzzle game. The Ice Gauntlet is a great final level, tricky and fun. I liked the graphics for the planets too. Only improvements to this I can suggest to add would be to have a larger image file for the larger planet sprites to make them slightly less blocky, and to add more levels even though there are plenty to play already haha. The sound effects and music was nice too, and turrets and homing missiles were done great.
