With some tweaks, my LOST level is really coming along. It went from 3 to 4 stars this weekend with about 250 plays and about 50 hearts.
I changed the ending to a smoke monster chase. I originally tried to put it on an emitter, but for some reason, gas goes back to its green color if you use an emitter for it. But I sorted it out, and the clever feeling you get when you come up with an elegant solution to a mechanical problem rivals any puzzle game I've played.
I love that aspect of LBP level creation, where you have to plan for every contingency and adapt the level mechanics and cameras accordingling.
Anyway, check out my levels if you get a chance fellas. I'm up to four now:
LOST
Little Big Indiana Jones
Inside Your PS3
Towering Inferno (a bit rough and damn hard)
