'Baba is you' is one of the greatest puzzle games ever. The sheer amount of levels and variations is just staggering, although I must say that it absolutely does become quite frustrating at the end, and you can see from achievements that very few people actually stick with the game. While 8% have technically "beaten" it on Steam, you can get that achievement quite early. I have given up after about 60 hours with the game, because it simply stopped being fun, but I still recommend this gem to anyone, just don't be a completionist...

EDIT: Just looked up at 'time to beat' that completionist average is 48h and now I feel very stupid... I find that kind of hard to believe, there were some levels I literally spend 2 hours on, and the full game has over 200 levels... (and I would guess at least 10% of those are very hard).
