Stunning graphics for a game jam! You can clearly see that 5 talented people worked on this game. I also really like the music and sound design in general.
The early game does feel a bit random with where and when galaxies spawn and it's way harder to progress when you are moving too much. The late game however gets a bit too easy with the increase in size and most importantly vision. I feel like you can pretty much survive forever once you hit a size of ~50.
Game is really fun and polished, though. I'm just being a tad harsher on the small details as I want to consider the group size and that there isn't really anything else to critize.
Good job on a really nice looking game!
