That's really an adorable little game and a cool interpretation of the theme. I definitely wouldn't have considered going the sci-fi route lol
Personally I'm a huge sci-fi fan, and terraforming in games is an amazing way of showing progress, I like how the planet gradually changes little by little (the flowers, trees and the ice slowly disappearing)
And honestly, I like the art style. The simplicism of it really adds to the cozy vibe, not sure how to describe it properly..
Obviously quick to play, but very fun!
