Hey, I found this game being developed. It's a first person puzzle game and looks quite good.

The gimmick is that you travel between two time periods. You don´t have any weapons, but you do have a tool that you can "tag" stuff with so they follow you when you travel through time. This can be used to solve puzzles or defeat enemies, as seen in this video:

Looks pretty cool. Sadly it looks like there will be a lot difficult jumping puzzles in the game. What do you guys think?
