Nice work! I liked the story and the concept a lot. It would be nice to have a few more challenges or twists in the levels, something to work around in order to successfully heat/cool the planet.

The menus and functionality are working pretty well, no issues that I could spot. Looking forward to playing again if you work on it after the jam.

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!

I actually liked your animations, they are distinct and weird enough to be memorable.

Some challenges would be welcome here. Meteorites, for example, that you could also turn hot or cold to destroy.
