Congrats on starting and completing a game/game jam as that's the hardest part and I think it was cute and great that your daughter to help you out with the graphics. In my mind I think the ship looks like ice and the enemies look like the are on fire which quickly tells me "Fire bad, me ice will melt" which is a great to convey information without saying anything. Wish you had the time to add some fun sound to compliment the artwork.
