There are quite a few puzzles to solve, but we managed to get out with 2 people. 45min is tight but still manageable. The difficulty of the puzzles are relatively on the easier side. There is one puzzle that requires a level of English vocab (both me and my husband are not native speakers so actually struggled a bit because we don’t know the word lol). If you are native English speaker you will be fine😂. One feedback to the owner is that we would recommend to give more guidance on which door/drawer was opened when we solve a puzzle. There are a couple times when we solved the puzzle without noticing a drawer was opened, and was stuck for a couple min without progressing until we noticed the drawer was actually opened:(
