Feels like on of those “idle” games popular on mobile phones. But without the donation part. There’s a character with indirect control.
The only things you can control is the character equipment, and even that works in a weird way. Once you replace piece of equipment, it doesn’t return to your inventory, but simply disappears.
Also, if your inventory overflows, items will start disappearing as well.
There is no experience until later in the game, once you build a specific building. And once you get the experience bar, it doesn’t affect your character stats, but only allows to pick a perk once the character gets a level-up.
So what you do most of the time, when you don’t pick the next piece of equipment, is building the world around the character. You do that from cards that you pick off the fallen enemies. Of course the cards are random. Everything in this game is random. So, you get to pick which enemies you’ll encounter, for example.
