Yeah... the game's developmental team seems to be not very good at debugging nor communicating with the general public.
Personally, I'm still mulling over which Dreamcast games to get with my refund.
Yes, programming isn't a simple endeavor when you want to make something like a real-time, part-sprite, part-polygonal 3D action game that has to run on a 200 MHz CPU.
However, if you are having too much difficulty in getting it accomplished in a timely manner, then you ought to have better, frequent communications with your community and/or bring in a specialist that can help you with what you can't achieve by yourself.
At the very least, publish a new screenshot once per week if you don't want to write a bunch of technical posts. At least then people will have something to look forward to each week and it won't seem like your project is dead.
