High highs, mid lows. Starting with the positives: the OST, art direction, and story are all great for a creature collector game — the OST especially, since I've got multiple tracks from it in my regular playlist. I'm also not usually a fan of open world games, but this one had me taking notes while I sank hours into its world, which says a lot. On top of that, combat has real depth thanks to the fusion and breeding mechanics, giving you a lot of room to experiment with team building. The bad: a couple of design choices here are baffling. For a story that's supposed to be about choices mattering, you only get one save slot — I wanted to see what it was like to side with each faction, but instead I have to commit to just one. That problem compounds with the ending lockout: you get shut out of the faction-specific endings even if you've met the requirements for the true ending, which feels like a slap in the face after putting in the work. Combat has its own frustration too — almost all moves sit below 100% accuracy, which doesn't add tension so much as it just annoys the player. On the creature side, the designs clearly have a lot of heart put into them, but none of them made …

Fantastic game. Love the monster taming and a pretty good story even for not knowing where exactly I needed to go for some of it. Definitely worth the price of admission. If I had to critique it, I'd say the moves should be a bit more diverse. Think Pokemon 1st gen- Dragon type only had one move, bug had like 6- each type ends up only having 2-4 usable moves in the late game.

Pokemon but instead of wanting to become the champion your character just wants to watch the world burn. definitely one of the best creature collectors i have played on steam many others push me away after a while but this one i cant stop playing

It's fun, the breeding feels too advanced for me though. I feel like I need a spreadsheet to actually pay attention to all the stuff that goes into maximizing the benefits you get from breeding. That paired with some clunky inventory navigation (playing on keyboard, would probably be better on controller but I don't own one) makes that whole aspect of the game feel a bit too tedious. That said the world is beautifully crafted and the story is interesting as well, so it gets a rec from me.

The game is great in a lot of ways but it lacks a really important component that makes creature collectors so good, and it's monster diversity the main mechanics of breeding and fusion effectively it doesn't matter what you collect because you can effectively max out one or two monsters and just give those stats to the others ones overall making new monsters and real strategy boring and pointless. Furthermore smaller niche issues are the controller support which is severely buggy and the save mechanics I find it more annoying than anything having to save before any potentially hard boss which I wouldn't know is coming up and lose any progress unsaved.
