Hey, good job on getting a submission in, and for doing your first game jam!
I understand that you had rl problems (I don't know what they were, but I get not having enough free time to do what you want, wish I could've done more on my game)
I like the concept and whoever did the art did a good job. The -oids are really cute, and I like watching them bounce around.
I also like the idea of balancing an ecosystem, until I need to destroy it. Maybe as like a sacrifice, that would be cool.
I don't know if that feature was implemented though, I didn't see anything telling me when I was supposed to kill them. And I also a lot of times couldn't really tell what the -oids were doing.
Hope you come back next jam and that you have more time to work on it! This is a really good start!
