This game is a masterpiece!
Even at this demo version point. I really liked level's design, secret areas, especially super one=).
I enjoyed the balance between enemy's amount and space: there are halls pretty filled with them, and at the same time there are empty rooms. So I haven't feel too exhausted or boring.
Graphics looks very nice, I was impressed by water textures. But, as for me, graphics must be more smoother, and not so pixeled, you know.
Demons are also good. Hope it will be more than 4 species in final version. There are some bug with yellow zombies with riffles: at first level, when they trying run to player, but he hides round the corner, zombies are disappearing and teleports to their spawn place. I'm not sure, but guess, it shouldn't be so. Also a few times these zombies shoots me through the walls.
Another kinda unique feature is katana, and it's modification. Maybe, player shouldn't start game with pistols as well, just for making a dozen melee kills.
Also having torch will be very helpful sometimes, especially around the dead-ends of corridors, where it's very dark. Btw, I stacked in one of them.
And, of course, book-look-liked keys! It's awesome. If they will have some description with strong plot's reference, like in Serious Sam for instance, but not so boring like there, this shooter will keep player tough till the end of game!
Also, secret's counter will be pretty comfortable feature.
Ok, I think it's enough for first impressions. I just fell in love with this game from the first sight on youtube, and haven't disappointed while playing it! I really appreciate your work, T19Games and wish you enough luck and energy to finish HellHunt!
Waiting for new updates and release!
