So, you're going to charge £30 for a game with a level cap of 10, an upcoming DLC that raises the level cap by a grand total of 2, five types of enemies, two bosses and two character classes? That's full price for a game with less visible gameplay than most flash games. Hell, I can't even actually FIND anything on this damn game other than this page, because a google search turns up jack shit, except for this page. Even a simple link to wherever the hell the site for this game is would help us to form a better opinion of it.
Just as an example, Dungeons of Dredmor has a higher level cap, more character class combinations (technically, there ARE no character classes), a lot more enemy types (hell, I haven't even seen 90% of them), procedurally generated items of all stripes, and all sorts of fun stuff, for a grand total of £5.49 (with the paid DLC).
Yeah, comparing this game with DoD is like apples and oranges, but I'm trying to make a point that if you're going to charge 30 bucks for a game, you'd better fucking deliver 30 bucks worth of entertainment. As it is now, this doesn't look like a well-spent £30. Maybe a indecisively-spent £3, but not triple-A game price. If you want to charge that much for a game, then it'd be a good idea to plan it all out so that your players are getting value for money. Not five types of enemies and two classes.
Also, avoiding infringing on the name of an old DOS game by adding one letter? If you're trying to avoid being sued over it, that's not a good plan. You can be sued on the grounds that the names can be confused easily (see the whole deal involving Mojang and Bethesda over the word "scrolls").
And as an aside, exactly how difficult is it for you to get screenshots of the game in action? Computers come with a built in screenshot key, and any image editor worth its' salt can crop it down to just the game if it's a windowed game.
