Thanks for your replies, sorry it took me a while to get back to this thread, being a small indie outfit i've just been concentrating on trying to finish features and sort out servers and a million other things
The technology is HTML5 - it's just HTML and javascript. It's admittedly clunky now - you can see other players move around in "real time", but it's not smooth - imagine a game like Civ where you play square to square. Having said that there's very little you can't do with HTML5 right up to and including full 3D so there's lots of scope
In answer to the concerns, I understand and have been aware of them - this is a RPG with bitcoin trading built in, it's not a thin shell of a game hiding a lottery. Prizes exist in the game but they are at the end of quests and are definately not games of chance. The prizes are there to entice players but really want I want people to appreciate in the game is the direct player to player trading via BTC. (I would actually also like players to be able to set BTC quests for each other, e.g you have a grudge on another character, you can hire another player for real BTC to assasinate their in game character).
Here's the details on the Bitcoin aspect:
Signup fee is 0.01BTC to create your character, after that you have to pay
absolutely nothing and can complete the quests and play the game without bitcoin (our tester completes the quests totally without btc). The USP for this game is that you can then trade directly with other players using bitcoin like so:

It's like an in game Bitcoin marketplace for players. As you can see in the picture, you always have the option to just pay in GP, Bitcoin isn't mandatory.
We use a notification API to register the payment and transfer the item when the BTC has been confirmed, the money goes directly to the bitcoin address specified by the user on sign up, we don't take a cut.
I canned the idea of being able to let people buy in game Gold Pieces for BTC as I am trying to avoid "pay to win" style games. We are effectively doing an open beta with crowdfunding so people who pay more get a little more (but not in a gameplay breaking way).
Launch early next week
