nothing happens on killing the boss, I ran out of time to implement my planned ending scene, same with the castle the plan was that most of the larger rooms would have areas accessible after the super jump.
The core movement and hit mechanics are definitely lacking I know for the next jam to work on that first ;) (as everything else flows from that). It is a bit better when you have at least one dash (the lightning) but still not great, and unless you really know the map (ie wrote the game) you'd never find the first lightning on first attempt.
Thanks really appreciate the feedback, this was definitely a learning jam for me!
