Hardcore gamer: 4.5/5: Review: Stephens Sausage Roll | Hardcore Gamer
IGN Hungary: 9/10: Stephens Sausage Roll - Teszt - A vilĂˇg legrandĂˇbb, legokosabb jĂˇtĂ©ka | IGN Hungary
There are not that many reviews out for the game at this point (if there was I would not link to IGN Hungary!). I am not sure if it is because review outlets think the game is too niche or because reviewers simply have a hard time playing through the game and, understandably, don't want to do a review if they feel like they only scratched its surface. Polygon for instance made a lengthy paper where they contacted several known indie devs who played the beta and published a gameplay video of them struggling mightily with some of the very early puzzles, which makes me a little worried in their ability to review it sometime before 2022!
Steam reviews are currently 95% positives out of 46 reviews (it should be noted a dozen of these reviews are from beta testers who, like me, have been waiting for more than a year to become sausage rolling evangelists - a bit like the Witness, it's a game you want your friends to play, not only because it is great, but so you can talk about it with them!)
