I made my first 3D game in this jam and struggled quite a bit, but I finished it in the end.

It is a 3D parkour game called Caller IDie, in which you leap across a cityscape to escape the endlessly pursuing Agent. The player has to solve puzzles that use different buttons that signal to different objects as fast as they can before the Agent catches up. The Agent's AI learns how the player moves through the map, creating shortcuts as to never make the same mistake twice.

Despite having a rough time with it, I learned a lot of things! https://ldjam.com/events/ludum-dare/59/caller-idie
