Just entered this into Epic Game's monthly Game Jam, this time around they're doing a huge one with a week long time table.
So that said, I made this in just under a week... I call it War Suns. Not sure why, but the name stuck with me...

here along with a few more screenshots.
It's a side-scrolling space-themed shooter where you play as a moon/planet/star and try to blow up other moons/planets/stars.
Currently has only 4 levels, each progressively more difficult than the previous, but I'm thinking about maybe making more levels for this at some point... In the mean time, enjoy the free demo.
