Yay! I am so looking forward to this game.
For once, I’m even considering backing it.

While I’ve never actually backed a Kickstarter project before, I have kept track of a lot of them, and I’ve seen plenty be funded and then subsequently fail.
Here’s some advice, take it with a pinch of salt, but it’s usually what destroys most Kickstarter projects:

Firstly, just because a project gets funded more than you asked, doesn’t mean you should make more. A lot of projects start off with a good plan, get over funded, and then completely fudge up that plan by using up all of the extra money. This is because of all of the extra development time, and unforeseen circumstances. If you get more than you originally ask, then use that extra funding as a reserve in case things go awry. Keep to your original plan.

Secondly, backers hate change, even if that change is a good thing. If soon after the project is funded, you decided to switch to a Day of the Tentacle artstyle, people would throw a wobbly (I wouldn’t, I’d love it). Just a word of caution.

Lastly, you only end up with roughly 74% of the amount that is backed. That is when Kickstarter takes their amount, and you pay the tax on it, and who knows what else.
Keep that in mind.

Sorry about the wall of text, I just really want to see this project succeed.
