[Reviewed in 0.1.3]
I get why it got a huge boom in the internet (meme wise), but the game is so generic, there is no other word to describe it this precisely, everything feels and looks generic, from the worst animations I have ever seen (Pals glinding over the water without swimming for ex.), to the all copied elements from Ark, Zelda, Pokémon (not that I dislike copied elements, but there is no effort to make them unique).
Some Pals are well designed while others are just ugly specially the begginers one like the cat.
Now about the gameplay, the core of the gameplay (which is 70% of your game time) is about capturing Pals ala Pokémon Arceus, same way but you need to weaken the Pal first, which can be really annoying and too much time consuming and it's just plain boring after a while, they could've gone the same rote as Arceus (Violet/Scarlet should've too).
The game have some good ideas and executes them ok, it's better than the current Pokémon games that have been stuck in the same formula for decades and have crappy animations and not difficult at all. But it's not good enough to be a great game to be played more than 20h, you just get bored of the capturing loop really fast but I hope someday (now that the devs have money) they fix the game and make it unique and not overly generic and boring.
