Was playing it this weekend, I'm not gonna be able to get on the TV this week b/c my brother owns the Wii and will be playing Mario Galaxy, so I figured I'd play some PC games, namely this, Lost Coast, and Ys 1 and 2 Complete (plus translation). So yeah...
People weren't exaggerating about its length, I've played maybe 4 or so hours and I'm already halfway through the 4th (out of 5) stages, the biggest problems with this game are:
-Reused assets - looks like they took all the HL2 textures and added orange to them
-Doesn't really offer anything "new"... HL2 changed up its gameplay style quite frequently and had vastly more memorable set-pieces, this game seems like it reuses a lot of ideas and gameplay designs.
-Repetitive puzzles - I think I've zapped cars into antlion pits about 7 times so far
-Stage 3 is spent mostly in the dark, so you need your flashlight, which'll run out leaving you in utter blackness. What is this, DOOM 3?
Well, here's hoping Lost Coast and Episode 2 (I will be getting Orange Box for Christmas, hopefully) are more interesting.
