There's a walljump style mechanic. The theme is represented in that you're playing the bad guy and, by the end, the heavenly light is chasing you and bringing you towards the True And Proper Platform game exit rather than throwing yourself into the spike pit. There was meant to be some audio explaining this as you play but time constraints got in the way! Glad you enjoyed it though!

everything you said makes sense, but the purpose of the jam theme is to create creative gameplays, not just the implementation of the theme via art or story. if you change the winning point to a door and make the player sprite a bit less evil-looking, you lose the purpose of the jam, I don't know if you can see my point.
