Basically the delay must have been known to the devs beforehand.
Which brings me to the conclusion, that you ran out of money and lied to the community about the progress of your project.
This would also explain the hasty ICO, which you started shortly after opening the thread.
While your alpha looks really nice and the whitepaper is really good, youre actions on the community are not to be accepted.

For me, this means that I will sell my Heat tokens shortly after you release them and will not reenter. Period.
