Ayy, beat this one. Very funny concept and I liked how you needed to kill your new friends to add metal to the world. Nice take on the concept. After I finished evolving one planet, I was expecting to have to make a solar system of several planets since I found a couple planets scattered about, but it seems to end after just one. It'd be pretty cool to have to colonize several planets if you add onto this in the future. Also, pitch black space is scary, man. I don't think there are any boundaries, so you can really get lost out there if you just go for it. Like others have said, having a starry background or something will make it feel less scary to venture off into the unknown. Also, why do I feel like you hid an easter egg somewhere out in space? Overall, very nice game. Thanks for making it!
