At the beginning the screen shows one single archivement of "look at the stars" so the player knows were to see the rule. But yes, is skippable by just closing the archivements and starting a level XD
Still I kinda like it that way, so the game is not only sorting pieces but also searching and interacting with the other stuff, if we had more time I might have added some stuff on the room like a functional hourglass on the table or some posters on the wall only visible during the aproaching the window animation.
Thanks for trying our game! :D
