Thank you very much for ALL your comments, they are extremely valuable for me. Next time I will include tags "oldschool" and "90's" in my prospective level description (or something alike). Moreover I shall pay more attention to detail and rooms' architechture, though I don't want to change my style in a profound way. It's a matter of nostalgia - a matter of having played Doom, when I was barely a teenager. Thank you for the bugs' report, I will look into it, however, the archs seemed to work ok with me (port ?). Just one secret, it's easy to find it. :)
Regarding Brutal Doom, I can clearly see, that some people either love it or hate it, perhaps due its excessive gore, even for Doom fans, and it's quite bugged (after playing several hours, you can easily state that). On the other hand, believe it or not, it's what's made me come back to Doom in general. I like the sheer gameplay of it. Nonetheless maybe I ought to reconsider making levels for one port only, as the target group might turn out to be much smaller than I could foresee in the near future....
Then I reckon, that I should rely on testers - do you always send your maps to someone else for testing before the final release ?
Xegethra, I'm looking forward to seeing your video. Please let me know, when you manage to upload it.
What else can I say ? Ah, I want to play your (all users) maps too, so I will check them soon (hopefully) and learn from much more experienced mappers. :)
