I played part of LIMBO not that long ago, and I really liked it. I remember those parts! But I probably got stuck somewhere and never finished it (I'd like to try again, though). I have something mildly similar to the first one in mind : ) We'll see how that turns out.
Don't worry about unoriginality, it's all inspired by other things nowadays, this game included. Thank you for the ideas!
If I make it worth downloading, I'll work on adding more platforms/OS support! You could test the Linux build : )
