Papers, Please for aircraft maintenance :-D
Had a lot of fun playing this, even with the missing mechanics you had planned. Beautiful artwork throughout, a real pleasure to play.
Only suggestions I have are sound, and making the time skip feature more prominent (maybe near the clock). Wasn't until Day 4 that I noticed the comment in the description text beneath the game window :-D
There's definitely the beginnings of a great little game here, and I'd encourage you to keep going with it. Excellent work (and your first game too!) -- very well done!
