I played this game up until the last level, and then I "gave up". For me, the combat really ruined the game. The puzzles are fun and the environments really are amazing. But the combat drags the game down soooo much. It's not fun at all to encounter enemies, it's just annoying.

So in short, play it if you want for the puzzles and environments, but know that you might (probably) not like the combat at all.
