Hello,
Right now it's very hard for me to reply to these types of comments as I am limited on how often I can actually get online to check this for the next few months.
However, Mog, to answer your question as it's the only I've been able to read, I wrote this explanation a few pages back.
It's take 9 years cause of this:
First 4 years - Written and drawn development.
Next year - Spent learning the tools and abilities of the RMXP engine.
2 Years after that - Making Kailis in full, in RTP and RTP edits only.
2 Years after that to this day - Spent revamping the game in Breeze V2 stylization and fully customizing every aspect of the game, as well deciding to release it into episodes, causing me to rewrite the stories more in depth for each section of the game, thus a longer, more enjoyable game. The results are what you are seeing and will continue to see grow and flourish.
