The design looks nice, and there's certainly a lot of bloom, but I had a couple problems with it in the time that I played, which granted, wasn't very long.
On recommended settings (as opposed to the maxed settings I usually run HL2 on, and smoothly, I might add), it ran horribly. Didn't check the exact FPS, but my guess is that it was running at anywhere between 5-10. And, because this mod seems to require a lot of control precision (picking up objects while dodging monster attacks, jumping puzzles, etc), this definitely gets in the way.
Second; Maybe I'm just an impatient guy, maybe my expectations for any and all things HL2 are too high, but the game failed to even remotely grab me from the beginning. No story introduction, no real reason for anything is given, other than that your hero spawns at a magic circle and has to run around picking up journals. I understand that alot of games like to reveal small bits of storyline as the game progresses, but I just gotta have some kind of hook that keeps me going, or else I'm just going to lose interest, which happened very quickly in this.
In the very first battle, trying to pick out little bricks and boards to throw while simultaneously running in circles to avoid getting killed, all in 5 FPS speeds.. not fun.
But meh, it's free. What can I say. The music sounds professionally done. The models look nice. Most of the sound effects are good, although oddly, things like the "Use" sound effect still have that same computerized-sounding "boop" from regular HL2, which kind of takes you out of the situation and reminds you that you're just playing a mod.
Maybe I didn't give it enough of a chance, and I'm sure I'll probably take a second look at it later on, but that's my first impression, and I'm already bored. :/
