Origin Within
“We cannot escape our origins, however hard we try“. ~ James Baldwin
The quote would be the principal idea of our LD27 entry.
The concept revolves around a protagonist who tries to break free from a certain place (A dungeon?). However, a curse prevents him to do so, as every 10 seconds his time would be “reset”-ed, effectively returns him to his starting place. Interestingly, no matter how many times the character position resets, the environment around him will not. He also retains his memory of explored dungeons.
Thus, exploring the dungeon, relying on memories, solving puzzles, obtaining power ups, and opening shortcuts would be the key to break free from the curse. The game would be a dungeon crawler with Nethack-ish view.
Currently, i’m using a spreadsheet program to design the dungeon (spoiler alert!):

It will be coded in Flash, and will be compiled as a web game.
