I got a little bit stuck at the beginning. How do you place the button in the room?
The cursor is a bit weird. Holding spacebar turns it red, which allows you to drag objects. Pressing left on any tile on the left side brings you to the gift slot, then you can hold space on it, and press right to drag it out, as long as the left middle space is empty.
Originally there was a mechanic to pull objects during the day by holding space, so there was more synergy between day and night time controls, but it created too many bugs and just kinda overcomplicated a simple puzzle game, so I removed it
