It's been an eye opener for me how little people are willing to take on-board in a tutorial level (this is a general observation not directed at any one individual), even if you explain a feature, unless it's pointed out in the simplest, most direct fashion. Think this is due to the large amount of product out there to try (so many demos, so little time), that people have a low threshold for any obscurity.
Who is this directed at? I think you're massively over-reacting. Only a few people have posted and I'm really the only one that pointed out some flaws. Everyone else generally like it a lot. I played HL2 a lot so I'm down for a lot of obscurity. Some of the puzzles were hard, but they were fun too... Turrets are turrets
Zenith, don't take a job balancing gameplay lol.
