The theme of the GMTK 2023 game jam was role reversal. My team came up with the idea of a villain trying to control the terrain of levels to hit the hero with a bomb.

Use WASD to move objects, and spacebar to toggle which objects are active.

Track Platforms
Track Platforms
Script that receives messages from the environment controller, and moves the platform along a pre-determined track. These tracks were implemented, because the platforms needed to be kinematic so the bomb wouldn't push them around. In the future, I would make the tracks collision areas on a track object for easier placement and development.
The trackStart lists hold coordinates for where a track starts that travels along the x or y axis respectively, and the trackEnd list is where the track ends. The lists trackStart and trackEnd will have the same number of entries for each axis.
