Some of the fonts are a bit basic, it it doesn't fit the overall aesthetic, which is really good.
I liked the puzzles, although I think it would have been better if you didn't have the option to scratch on the doors which cannot be opened yet, because i thought i was scratching it in a wrong rythm. Especially the airlock door was confusing why i couldn't open it.
Great music, great art, great gameplay, solid game overall :)
