The game does auto save quite often, you should check those. I'm fairly certain I have it auto save right before you start the escape room.
went back in time and started fresh. Back in the escape room. Solved the Simon puzzle. I have all but one item. I can’t get the space suit open. I cannot get up to the train. I cannot open the box under the colored boxes. And I have only found the 6 and the 8 on the sticky note. Any advice would help. I have both keys, the sticky, the notebook, the screwdriver, the fishing pole, the coins and the hammer and the ladder.
