Great for a school project, and not a bad proof-of-concept for a remake or separate Assassin's Creed fan game. Once published it could have benefited greatly from basic refinements to elements like collisions, but it's impressive enough that the prototype actually released. This is the only fully 3D Assassin's Creed fan game I've seen released in any form that somewhat manages to handle parkour and level design.
I know it's unlikely to see the project files released, but would your team consider linking to the assets and plugins used so others can try to create Assassin's Creed-style fan games like this?
