- in first screen, the clickable tutorial book should be 4 times bigger, make it very obvious
- the first puzzle should be easier? we don't even understand the goal of the game yet, and we need to rotate the chair? this should be level 3
imo you need a lot more UI feedback...
- preview to player when they are dragging object into an invalid position? it is annoying when the game snaps the object back into inventory with no warning
- show to player when the object is in correct place and giving progress toward next level... see zipzap
good progress though, the game concept is pretty clear and I was able to complete it
