To answer this question to the best of my ability, I must make it known that the current release date of “Summer 2015” is completely ambiguous and is ONLY a Tentative Release Date. We WILL push the film back further if we feel it is absolutely necessary so the team can release a product that we feel is up to not just the expectations of our audience, but our own expectations as well.
One of the things I would also like to mention is that there quite a lot of people working on Journey of the Spark who have worked on other projects in the community and know what to expect and know what they are doing. The reason for the delay in the film’s release is simply the fact that films take a LONG time to get made and require a lot of resources. There are a great number of people working on Journey of the Spark who put a great number of man-hours into the project just about everyday despite the project being a solely voluntary experience.
Hope this answers your question!
