I already spent my "pledging budget" for this month. But, hey, next month is close
Anyway, I like the idea behind the game, but as a newcomer into the indie business, as someone who is not known, it is pure insanity to "demand" 300,000. I know it might be justified and probably correctly calculated, but still. People don't know you. This has nothing to do with your qualification, which is obviously there, but it is completely different with Brian Fargo and/or Tim Schafer. Those guys have fans that are fans since ~20 years. Including many, many people in the press. That is why they are successful, not because of a good idea.
In short: I am really convinced you should have aimed lower, probably with another game if this one really needs that much.
Also, the pledges... Cheat items? "Limited" dungeons, what good is that if you cannot share and discuss the experience with other people? "Limited" pets? A photo in the credits? What the ....? To me, all of this seems strangely elitist and actively discouraging. People most certainly don't spend 500$ on a game to appear like a "king" to other people or themselves, they spend that much because they believe in the idea. But if you get a sh*tload of cheat and elitist items when you give that much money, you'll certainly feel like an asshole. I know I would, even or especially when that was not the reason why I wanted to spend that money.
All of that said, I still wish you luck, as all doubts aside: the game sounds interesting.
