Thanks a lot for the kind comment. I'm not sure 3D is adding anything to the game, but since I do 3D on the side I'm trying to use it as much as possible !
The witch was suppose to add a bit of complexity to the level... but I lacked time to fully code her properly.
For now, I'm not exactly sure I want to add new levels as I might want to work on something else... but who knows if there is more people asking !
