The cover art for this game on one of your comments drew me over here.
Art and UI look great, though I think the smaller text could use a more readable font. In my experience with games in this jam that use the mouse for spinning, it’s kind of a difficult mechanic to use. A larger, custom cursor would help me make sure I’m keeping my mouse around the sun and keeping things spinning properly.
This game feels like a good starting point for something more fleshed out, I’d love to see anything else you might do with it. More focused introduction to the planets would help me understand them better; I found myself buying Mars and Jupiter and just spinning the heck out of everything non-stop.
The transitions on the alien invasion and when losing could use some better pacing, and I found the XP flying to the edge of the screen very distracting. This is a really neat-looking game, though, and I think it has a lot of potential.
