I participated in my very first Global Game Jam in Puerto Rico this year, and the theme was "Roots". We took the literal approach and our programmers worked on an auto-battler in which you use fertilizer to purchase the root vegetables that will fight for you. My tasks were to model and texture all 3D environmental assets. I did this all within a week after getting home from work, and it was definitely a fun experience.

A little gameplay. I added the sounds on my video edit since we didn't have time to upload it with sound effects or music.
