This game is a lot like a hybrid between Digimon and Pokemon, with a much closer lean to Digimon in the storyline.
Challenging yet fun digital world with complex mechanics and a heavy incentive for the player to explore and learn from their environment and everything and everyone in it.
Lots of hints and tips hidden around the game too.
I like this game, so I'd recommend it.
It is more challenging than other Monster collector/battling games I play, but not to the point I'd tell people to avoid it. Especially since there is plenty of tips and hints and other things to ease and help with the learning of the game.
Very good game.

Got this game on sale without looking too closely at it, and as I was playing I realized it was heavily inspired by one of my favorite games, Digimon World (PSX). It's got the aesthetic down, and manages to pull the digital/analog mixing much further. There's wires and plugs built into the scenery along with natural trees. Tamas consume floppy discs alongside mushrooms and meat.

It doesn't allow it's inspiration to prevent it's own identity from shining through, however. While the Digimon World drew its inspiration from tamagachis, this game is more aligned with a Pokemon style turn based battler, though on a much deeper level. Every battle requires much more consideration about what techs to assign, when to use them, the effects they have. I've found that to some extent, the goal becomes to find a way to make a totally broken Tama, rather than just leveling up until you can beat your opponents. And the game gives you lots of tools for doing that.

That said, that is kind of the big downside of the game. The pet raising is mechanic *heavy*. Every level gains potential, which requires consideration for how to distribute stats. Every Tama needs to be rebooted every so often to increase the level cap and get more potential. Tama must learn techs by seeing other Tama use them, which means finding out which Tama use which techs. And there's the breeding system, which I never really got into because it honestly all of these systems was just too much.

But that's also kind of the charm of a game like this. It's got a unique thing going on and it's not perfect, but it's clearly made with a lot of passion that comes through in spades.
