I should just leave this alone but this needs to be said. If you're not transparent and honest in your Kickstarter, you could potentially burn backers which in turn can impact other developers trying to raise funding so I'm just going to say this and then bow out...
I apologize in advance if this comes off as harsh but not being transparent or honest in your Kickstarter is really disappointing. I'm all about being conservative with dates so I don't blame you for that but that should have been clarified that in your Kickstarter. Your stretch goals just list stretch goals with no dates or impact to dates.
If you can finish the game in 4 weeks, then either (1.) The game was clearly 95% done already or (2.) The scope has been dramatically reduced since the Kickstarter was successful. A game 4 weeks out from being finished doesn't meet these descriptions from your Kickstarter:
"This is the project we desperately want to make, but we can’t do it without your interest and support."
"We've managed to create a playable pre-alpha for 12 Is Better Than 6, but this game cannot be made without your support. If you decide to help us, we will be able to finish the game..."
Doesn't sound like a game 4 weeks out from delivery, does it? Sounds like one that needs money or it will fail... In fact you specifically state that:
"The team has been working on the game for one and a half years now, and over that time they took it from concept to a pre-alpha demo... We are currently about half way through development, with a lot of features already in place."
78 weeks to get to 50% and 4 weeks to 100%? Would I have backed the Kickstarter if I knew you didnt need the funding to finish it? Nope. And I'm probably not alone there. I would have waited and bought the game on release (cause it does look like a really cool game).
Releasing the game early should be a good thing, and while I'm still excited to play it... I'm just disappointed that you guys weren't honest about where it was in development. Not being transparent about the game being further ahead in development than it was is just as bad as being way behind schedule and not being honest about how far behind schedule you are. There's just no reason to not be transparent if you're asking for money...
