HAHAHA the beaver taught us everything we needed to know, including how to eat him! What a dedicated teacher!
Really cool that you noticed the billboard assets! We had to find ways to make things work within the jam's time limit, and we're pretty happy with how it turned out!
I had never heard of TrenchBroom before, but it looks like something worth checking out, especially if we ever make another retro FPS. Thanks for the suggestion!
