Didn't get as far as I would have liked during the jam. I definitely want to continue with the project as a mini action/adventure game.
The jump was as exaggerated as the run speed earlier, but I toned it down slightly.
I've been looking for a (new) way to download actual map terrain into 3D environments, so it was great to find OSM to Blender plugin. It could be really useful for background environments, or reference for scale, etc.
