Hi Mark, I tried out Mac version. It seems to work perfectly.
It's a cool game. I came up with a few suggestions, but they are mainly just minor things that would add to the polish.
-It would be good to have a scroll bar on the popup text boxes. Text boxes don't feel right without it.
-"Press A Key to continue".. I thought I was supposed to press the "A" key to continue. Which would work.. but I think it should say "any". But maybe it's just me.
-Save files go straight into the game folder. Apparently, on mac you don't necessarily have permission to save there. So you are supposed to save in "~/Library/preferences" or possibly "application support".
-Graphics are pretty nice.. certainly better than I could do.. but I think they would be much nicer with alpha for smoothing the edges. Seeing as how they are 3d models, all you would have to do is change a rendering setting to get alpha. Of course that would probably be a big pain to do at this point, and maybe the game runs faster without using alpha.
-When you config your keys, you can set everything to the same key. This makes sense for the shoot and strafe, but locking the other ones, so that this isn't possible would better, I think.
Well, I think the game is very good and ready to release. Feel free to ignore these comments, because they don't make much difference overall. btw, this is on a new eMac.. I don't know the exact model because it's not mine.
