As someone who has played tons of difficult games and has enjoyed the said difficulty, Stephen's Sausage Roll isn't the one which I could describe as fun in anyways. The game starts off directly to a map where it all seems to comprise of difficult claustrophobic puzzles where you have no space to move or rotate around which in turn allows no room of error. The mechanics are very simple but the starting puzzles provide little to no room to build a visual understanding of logic which can be developed to understand the steps to reach the solution. You have a 5x5 grid with 3 or 4 grill and multiple sausages right off the bat. The calming music doesn't help counter your frustration as there's no "Hey I did this puzzle feeling" because it just ends.
There's plenty of sokoban games out there which are creative, mechanically simple, fun and/or nice. I may comeback to this for some other day but I didn't find this fun in anyways today.

One of the best puzzle games ever made. It is basically peerless.

Possibly the best puzzle game I've played on Steam - I'm not typically a Sokoban player but this really hits the spot. The mechanics are limited but they carry a lot of surprises. Each puzzle bends your brain without feeling like you need some secret knowledge to figure out what the designer was going for.
