Good stuff! Just finished it and must say I was pleasantly surprised by how good it was. Really liked the mix of learning about games and playing a game at the same time. The puzzles were challenging but not impossible. The choice of games was excellent and the each of the more polished spaces felt close to the games they represented. At the beginning I thought there was too much text but I was happy it was there to read about the games I didn't know.
The performance was good on my machine but could definitely be improved considering the size of the game.
This is what museums in real life should be like!
