Took me five hours and I finally did it! Muahahaha
The difference of this and the previous one:
1) The pit is twice as useful
2) The canon will mostly get disabled before the saw
3) You just need to fall down and it leads you the pit!
Grats, that looks a lot better. The cannon is in a good spot since hopping all those islands can be tough with bullets coming your way.
I still think your platform and red guard could be placed better.
The door should be in the lower half forcing the thief to climb up the right column. If they mess up, and end up moving left, they'll glide right into the pit. You should try it out.
Your platform just helps by cutting off a possible fall towards the pit.
Place the platform to the right side the bottom hump with half of it hanging over. This will force people into the pit if they fall down the right side in a wrong direction.
The Red guard can help reinforce the top row, or maybe defend the climb up the right column.
Try it out and let me know how that goes. =)
