Wow! Its so cool to see a fully fledged FPS during a 2 day game jam. I really love the stylized castle surroundings, and the gameplay looks solid and fun!
My small critiques: the asset for the grass seems way more detailed than the surroundings, even if it is a bit pixelated. Maybe something a bit more geometric? The difficulty ramps up really quickly, I think that you should get your player comfy with controls, abilities, and different weapons before you throw them to to wolves.
Overall, I think it is approaching a cohesive design language, and the mechanics seem solid. Shooting the guns feels responsive, which is really hard to achieve! This game is an achievement especially considering the 48 hour time limit! Good job to all your team!
