It's a great idea although I don't personally like the art style, but guns of Icarus was pretty lit, so when it gets a full release I might consider purchasing the novel but as of right now it doesn't seem like I'll even play it, although I would like to see where this goes before I put my money towards this
:edit: after looking at the indiegogo page and seeing that you offered a $10,000 one that I misread as $10 and almost backed it, I looked at your statement saying that this could be one of the biggest western VNs like ever, I know that 700,000 words sounds like a lot, but in reality it's not really that long, it's only about 10-12 hours depending on how fast you read, although I don't care about length. If a VN gets me to love each and every character, even the bad ones, then it can be 7 words long as long as I feel depressed after it's over because it's well, over.
(jokes on you I don't need that mousepad, that scratchpad has paper and paper is a nice mousepad for people who are well broke after paying that much money for a computer)
