Well done on putting together a chill game with an interesting story in the span of the game jam. Reading below, it's great to hear your plans for progressing the game, and I think there's some real potential here for a really solid experience. I think some degree of extra challenge in the later levels would be cool, such as obstacles on screen or a fuel gauge for your beams. Otherwise, well done for making all of the assets yourself, and a great start with Unity's animator!
