The puzzles are top-tier, they actually make you stop a minute and pay attention on what you suppose to do. Probably the best puzzles i have seen on a Survivor Horror game. The radio mechanic is quite interesting.

The rest is a big "Meh, whatever..."
Combat is ok, i guess... with some modern accessibility bllsht.
Enemies are repetitive and boring.
No real final boss.
Lacking soundtrack .
Story is some 2deep4you crap.
Characters are non-important.

Puzzles are only worth thing of this game.
