Many thanks for your detailed response, I appreciate you taking the time to give advice.
I'm glad you think the openness is helpful - I was worried it would just come across as entitled and whiny.
And I've made note of all the points you raised for the Kickstarter campaign. Ideally, I won't be offering any rewards that need to be shipped physically (no Mr Gaspard body pillows - sorry) and my initial thoughts were for rewards like extra game content, either within the game or in emails etc.
Basically anything that would cost me time, but not much else since I don't want to increase my funding goal any more than I have to.
And thanks for mentioning that some people don't pay what they've pledged. I have heard of more than a couple of Kickstarters that didn't deliver on what was promised, but I didn't know it could work the other way as well.
Hmm, yes, the pricing of Heaven's Grave was a concern of mine.
I tried to see if the price was the cause of the low sales by running a couple of discounts both here and on Steam, but sales didn't appear to improve much so I wondered if it was the premise that was putting people off, or the writing, art or something else.
Perhaps it's a combination of things including the price. It's certainly something to look at in future (and the only thing I can affect now the game is released, ^_^)
Anyway, thank you again for your insight - at least, I've a better idea of things going forward whatever path I end up taking.
