You play as Artemis trying to apply to become the goddess of the hunt, while a misogynistic asshole (Hermes, I think?) tries to stop you through the power of bureaucracy, and favoritism towards your lazy bum of a brother, Apollo.
And you do it by matching three things together to create bigger things. I swear I've played at least one mobile game like this.
The controls are clunky, and the challenge levels are made even trickier by how things start moving once you create creatures, making it harder to smack three of them together, and they poop out lower-level items that get in your way, and you have to keep combining them so they don't flood the board before you can achieve your objective.
Honestly I preferred the little open-world section without the time pressure. You just have to solve puzzles, deliver items, and fix up the place.
