Long story short: The game was pushed back for marketing time.
The real story:
Recently I was approached by an individual who works for a company (who shall be unnamed for now) who offered to work with me for the marketing for Irritum. We weren't able to immediately work something out, but we now have an agreement in place and are starting to work on publicizing the game further than I would be able to.
They said they would need 3-4 weeks prior to launch to start marketing, and the original release date of August 16th would have been too small of a window for them. So I pushed the game back to September 6th.
The individual who contacted me did marketing for several other indie games, many of which hit their goals and have been successful (I am sure you have heard of two of them) but they will stay unnamed for now also because I don't want to reveal who this individual and the company is without their consent.
Anyways, they approached me and offered to do marketing for the game. This gives me more time to focus on the game, in addition to reaching a wider audience.
On a personal level, I am excited. This could open up a whole new level of success for the game. Time will tell though.
Thanks for reading.
