Summary: Amazing production, immersion and story!
Puzzles: The puzzles were not particularly challenging. While they were unique, many were more like dexterity/reflex challenges rather than thinky puzzles.
Immersion: Best production room I have ever done and they really pushed the boundaries on the experience an escape room can deliver! I would give a 6 for immersion if I could. From start to finish, I really felt like I was on a space ship, and the tech was outstanding.
Execution: The game is split team about half the time but you don't miss out on the puzzles, except for 1 minor puzzle, which is great. Each team also gets to make some decisions that can impact the other team, which also factors into which story ending you get. There was one point in the game where the one team finished their part before the other and had to wait around for a little bit.
Group size: We had a mixed group of 5 beginners and experienced people. I would say 4-6 is a good amount depending on experience level. Any more and it would be way too crowded.
