Kenneth-
I'm curious, have you sold the game?
I want to be as helpful as possible...
First, I would try to make your game as low cost as possible, your much more likely to get someone to spend 5 or 10 dollars (still unlikely). I worry that you have placed so much of your heart into this game and might not get the satisfaction or money you are looking for.
Start small, make games free or shareware, this way a publisher will take interest and possibly fund a future game. On the look of the game, PLEASE take some time to look at what your competition out there is. How do I say this...your game lacks a certain sense of art direction
Take some time and play as many pc games or demos you can and take notes on how they do lighting, animation...
You can learn a tremendous amount by studying other games.
If you are submitting your game for public consumption, make sure you can handle the negative reviews!
Lastly, make your specs MUCH lower, not just slightly, MUCH. Your minimum requirements should be something like:
Minimum system requirements:
Windows 98/ME/2000/XP or Linux
AMD or Intel 800 Mhz processor or better
Direct 3D capable crad (64mb or 128mb geforce or ATI)
256MB of free memory
Mouse and Keyboard
I know it sounds low, but thats what most people have.
Try to run your game on a pc like this.
I understand you are an indi developer, but if you plan on selling it, be prepared for the competition!
