I detect some local folklore in the design of that stage, or was it inspired by a childhood dream?
It wasn't inspired by a childhood dream, however, both local and foreign folklore may have inspired me to create such an atmosphere but I didn't have any direct influences by them. I just "went artistic" in my mind and created what I view to be three different views of beauty based on the different periods of my life. I just wanted to express those while adding a unique spin on the "survival" mode of typical LBP levels incorporating a hidden puzzle element with an environment that changes slightly depending on how you choose to play. Of course, because it is deeply artistic, there are many interpretations that can apply.
I've recently bought LBP2 and I'm gonna be working, whenever I have free time, on a new level definitely inspired by the Metal Slug franchise. It's still in the pre-design stages so I don't know if I'll be trying anything original and ambitious but as soon as I get it running perfectly I will post it on GATT.
I was working on another level for LBP that would've been original and ambitious but I ultimately scrapped it for my Metal Slug-ish level. I may step back to it once this level is completed.
Btw, did you try out my first level: "The Experiment" by Sudesh?
