Incredible fun! This really feels like it could be easily a fully featured game. An astouding level of polish for a week. I could nitpick about some game crashing bugs upon game restart (if you used GameMaker Studio 2.3, don't use game_restart() anymore, is broken as hell) but to be honest this puts my effort to shame.
And the most important part, this game is FUN. I played to help with the ratings, I finished it three times because it's really fun.
Great job!
