Cute. but NOT worth $20...
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.
Highly underrated game. Very much give it a thumbs up. Charming! Funny! Very British!

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.

Świetna gra o zaskakującym i świeżym pomyśle. Utrzymana w doskonałym klimacie między absurdem, a angielską herbatą. Można grać na jednej kopii. Na trzeźwo i mniej. Gra jest dosyć krótka, ale urocza.
The sweetest, funniest co-op puzzle game I know. It's just a few hours playing, but packed with humor and doable puzzles. Play it with you girl/boyfriend <3
MUY BUEN JUEGO ENTRETENIDO Y DIVERTIDO PARA UNA TARDE CON ALGÚN AMIGO
키보드 움직임이 상대적으로 넘 느려요. 퍼즐 설명이 있었으면 난이도가 대폭 하향될 것 같아서 오히려 불친절한게 재미있었어요. 차는 그럭저럭인데 스콘퍼즐 조작감이 별로에요. 그리고 게임이 조금만 더 길었으면 좋았겠어요.
This game doesnt lack of creative ideas or realism xd. Graphics are cartoonish which is quite sweet. I liked the music too. The minigames are also fun but sometimes you need a little time. The dumbest thing is the fight with the space monster. its weird and you only have one try? And for 1.5 hours of gaming its unfortunatelly not very cheap. 8/10
Perhaps I'll get to writing my review after a perfect cuppa... I'd rate this game a 6.1/10
This is a fun co-op game. Not too long and can play through in one setting.
