Basically an isometric hack'n'slash, with unlockable abilities, and upgrades. It starts out very simple, but it does layer on more complexity as the demo goes on. A grappling hook, ranged weapons with limited ammo, a projectile deflection upgrade to the melee weapon. Neat stuff. And it seems to love its hidden secrets.
You don't have much health, but you get potions you can recharge at the local "bonfires".
It was fun enough, though I think this is the kind of game I wouldn't really enjoy without an infinite health cheat. Getting reset to the bonfire every time I die just feels like a nuisance, even if I'm able to unlock a few shortcuts along the way. I do appreciate that you don't lose any money or items, but I'm not a huge fan of backtracking.
I'm not going to strike it from my list, but I'm also not going to make it a big priority.
