It's fun, but does not have much replay value. While the story is pretty generic, the levels have enough variation and are fun to play. The puzzles are ok in general, with a couple of really good ones and a couple of bad ones thrown in.
This was a very fun coop game. Similar to We Were Here, this game focuses on quick wit and communication to your partner. There were a few sections I think could've been tweaked better but overall very good balance of fun and challenge.
