really cool neat little game!
I see a lot of potential, (I'm gonna go a bit ideological so ignore if you don't like that BUT) you could easily teach people on how planets are habitable for us humans and all the specific factors that go into that: atmospheric pressure, composition, greenhouse gasses,ect... If the game was ever to be expanded. Which you could also then use to showcase why climate change on our little dirtball is so important! :D
Really enjoyable, very nice graphics for such a small game and overall great, keep at it!
