FBIV | Bones (1player)

Maybe put one of those Xs on the first bone so it indicates to slam it. That will teach the player that Xs and bones can be slammed.

Would be cool if the slam attack worked on boxes all the way to the floor. Or even busted all the boxes nearby, like an area of effect.

The larger launch pads timing feels off. Maybe use a single keyframe to move it up. Add springyness and pulse it on--something like that.

The imp stuff works well! Though the switch looks like it could be used by the imp, in retrospect.

The spring launch felt a little slow. For more control, you could use a force applier along with the visual.

Going inside the skeleton is a really fun idea! But it's very difficult to play because you often can't see.
