Good fun game, but this is really a $9.99 game... Trying to bank off of people's Nostalgia for old games is just a Greedy Business Tactic... Yes it's awesome you added some graphics to a mostly text based game, but come on, 30 bucks, really??? Not too mention it's been out how long now, Years, and you still have yet to fix the bugs within it...
Greed does not look good on any Indie Developer and when one tries for the big money, it makes all Indie Developers look bad... That's not too say some Indie Projects aren't worth it, of course they are, but when it's just a Graphic Remake of a Text Based Game, there's nothing original here...
You're not worth 30 bucks, accept it and drop your price... Think Quantity... Selling a game for 30 bucks and you sell to 100 people, Yea you made 3 grand, but sell a game for 10 or 15 bucks and sell to 500 people and you've made much more...
And the fact that this is purely a download, there is no overhead of Discs and Cases to worry about... Just keep the electricity flowing to the Server so people can download it and it's all money in your pocket...
Don't be Greedy, be an Indie who thinks of the Players...
