THIS is a game I would pay $$$ to D/L on PS3/X360!
What an incredible work of simplicity and brilliance! This is the kind of arcade style game I would pay $$$ to download on something like Xbox Live or the PSN! I love it!
You could cash in BIG time with something like this! If you DO (and please, PLEASE do) decide to make a version for consoles and make some moolah on this, I do have only a few suggestions:
1. More levels!
It would be great to see some even bigger levels with interactive sorts of parts, like doors you could shut, barricades, defensive weapons systems you could activate, etc.
2. More weapon types and upgrades!
Dual pistol upgrade, minigun, Laser rifle, flamethrower, and some rediculous weapons like a satellite based beam cannon, air strike, a mech or tank you could get in, or a nuke. Maybe you could even have some defensive style weapons like a forcefield grenade, sentry robot, decoy, or turret based guns.
3. More enemy types!
How about super zombies, zombies on fire, super demons, etc. With all those new weapons and such, you'd need some more challenge as well to balance it out.
4. Here's the coupe dé grace... MULTIPLAYER!
Just imagine... having up to 7 (you'd have to do either online multiplayer or on the PS3 for its 7 controller ports) people at once standing together to face the zombie horde, or against one another, having zombies to send to their friends' base in a way similar to the weapon upgrade scoring system.
With these suggestions implemented, you could very well have the next Geometry Wars on your hands! Anyway, thanks for reading this, and hats off to your great addictive game! Can't wait to see what's next!
