First, the overall concept is nice. I might find it useful as a developer.
I have numerous complains about the details
- it looks too much like some sort of crowdfunding, it's confusing and not needed.
- the main goal "to get the hype at the right moment" is not what I look for (OK, it's nice and everything but not the most tasty one for me), I would rather use it as a platform to:
* get to evaluate my concept (if there are fans for it)
* get in touch (ability to message them when the game is ready) with people who said they were interested
- I'm not sure the time limit "days of campaing" is good (but I have no other idea and see some benefits, so just pointing out)
- as others said, the domain name sux
I would recommend something like "ILikeYourGame.com" or "ISupportThisGame.com" or "IWantThisGameToBeMade.com" (and don't be afraid of it being too long, being memorabe is far more important)
Generally, I like it and would probably use it, but I would rethink how it works.
