hey great work on your submission!
I really like the eerie atmosphere, especially on the first level. The sunset really makes me feel anxious, streets and cities being so empty (aside from the enemies) also add to that feeling.
The gameplay also has a lot of potential, but I think the core gameplay loop needs a bit of polish. Although I imagine that you have a lot of ideas on how to improve it, just couldn't put all of them into practice within 10 days :P Personally I think it's good to enhance the experience of being a long-ranged character who is weak up close, especially before the undead: maybe make it so that enemies have a bigger detection range and give player ability to hide, to really emphasize the stealth aspect of being a bow user + add even more suspence to the game. I would also add some offensive abilities to the necromancer, as right now it's a little weird that I can just shoot them so easily once I find them. Maybe once you find the necromancer AND the necromancer notices you, they command their entire army of undead to swarm you, so now all the enemies are on alert and trying to get you?
All in all, I think it's a really promising entry. Good work on your submission :D
