That was fun! Played through it twice. Once with the rogue because stealth archer OP, and then with wizard and knight because my wizard died :D
Loved it immediately in the first level, when I saw the skelly behind the door, but the other door had a hole I could sneak through to backstab him. I knew this was a gem immediately :D
I think the ambient atmospheric music didn't play on my first run. When I started my second run, I heard it. Or I totally didn't notice it during the first run.
I would love to see more content and challenging enemies that require a more tactical approach. Right now rogue is OP because of infinite one-shot ranged attacks, that don't aggro if you're too far away. So there's no reason not to use Briar. But in combat the fighter is OP because your strikes are way faster than the enemy strikes. And the wizard has a nice ranged attack but is gated by mana so that makes the rogue more useful because of endless amounts of arrows with no drawback or stamina cost.
So next round when you're grinding another 2 weeks straight, I'd love to see some more enemy variety. Both in what they can do and how they act (patrols, social aggro, noise investigation, improved pathfinding so they don't get stuck, etc)
Also, I loved the verticality :D The capsule collider makes it a bit hard to be at ledges because you'll slide off quickly, I think it would be better if it's on/off a surface completely rather than the gradual slippery slope feeling it has now.
Anyway, lots of nitpicking, but excellent job :D more pls
