There is typing weakness and resistance. Each Pal can have 3 moves and you can swap out the moves from whatever they know and you can also teach them moves using move fruits (aka TMs). However you don't directly control your Pals. It's real time action based combat. So you are running around shooting and dodging and your active Pal is doing the same all on their own. So no, it's not a pokemon game, it just has some elements of it in the form of catching, leveling, learning moves, breeding, and having some pals prove utility skills.

The combat definitely lacks depth, but they have also provided other gameplay elements to offset. Base building is a big one. Your Pals can be assigned to do jobs in your base, and different pals are capable of different tasks. It's first and foremost a survival game and setting up base automation is a core part of that. Your base occasionally gets raided by wild pals or bad NPCs that you have to fight off.

I actually agree that I don't think this game will last long, for me at least. But that's fine. Not every game needs to be a forever game. For $26 on steam (or included in game pass), I've already had enough enjoyment out of it just in the last few days to make up the cost. I mean, that's pretty much the cost of going to see a movie.
