'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).

I'm in the later part of the game and I feel really stupid. Some levels are so small I feel like I can understand all possible strategies but none work. Lovely game overall though, highly recommend!

except both Baba and Keke are bouba.

I was once asked to contemplate the frightening concept of kiki tea....

I think this indicates the features from vision and audio got aligned properly and hence we know what is what intuitively.

The effect replicates in languages with other writing systems.

That seems to me like it just shifts the problem one level. Why are K's and Kikis spiky and why are B's and Boubas round. Why is it universal too across people with different writing systems and languages.

In Telugu, k is one of the smoother letters: కి (ki: the squiggle at the top is the i vowel sign).

I think it is related to the physics of the mouth producing the sound, and we do a form of synesthesia: doing b-u-b seems (to me) quite smoother of a transition than k-i-k. If I stop blowing the u sound my lips close again; when I finish the i I have released the muscles and I need to hold again for the next k. It al feels more sudden an explosive with k. Also the b sound you voice it (otherwise it would be p).

There is a pre-print which claims to have found this effect in 3 day old chicks. Given three day old baby chickens are not renowned for their literacy skills, it would point to some much more deeper origin.
