Reviews
This is a fun co-op game. Not too long and can play through in one setting.
This was a fun game and required you to cooperate. It was very enjoyable, the jokes were pretty funny. I highly recommend it for any couple wanting to play a fun game together. It was silly and had some pretty mid weight puzzles, but overall was enjoyable. I recommend it.
Really cute and fun little coop game!

For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
