So I've been working on a tower defense style game the past week, even without establishing a guaranteed theme, and things are coming along very nicely, sort of.
I've run into a roadblock and lack of motivation due to artwork. I have to be in a certain mood to work on pixel art, and, I'm just not in that mood now. Not to mention the amount of time required in order for things to look good.
I've established that I want the game to have a hint of RPG elements. Right now the game is themed around medieval fantasy. You place siege type vehicle units down (ballistas, catapults, cannons, so on) and the invading creatures are your typical skeletons, ghouls, slimes, dragons, and whatever.
Taking on RPG elements, there are boss waves that require certain strategies and defensive units to take down. On top of that, every defensive unit has special abilities and micromanagement. Players will have to be interactive with their defense units to use the required abilities and even manually select invading creatures to take priority in what the unit should attack. Placing "towers" and watching what happens wont really be plausible (for harder modes anyway).
After making a ballista icon, which didn't look half bad, I came to a conclusion that the medieval fantasy theme might require too much artwork for myself. So, I've decided to look into a space theme. Ships aren't too hard to make and you really only have to make one icon and flip it. Basically the map would be an asteroid field of some sort and "towers", most likely turrets and rockets and what not, would be placed on top of the asteroids to fire at the invading ships.
The only problems with the space theme is it's hard to make it make sense and it would basically mean only one type of map theme (space).
Aside from gameplay, I did do a lot of work on the game's interface and other basic elements which could easily be used for any type of game (and probably will be). The window is 100% custom with beautiful looking elements (that actually looks sort of space themed, which might give the space theme another plus).
The game has been designed from the ground up to work (theoretically) with BYOND's upcoming Flash client. And most of the basics are finished, just needs to be filled with content.
With all that said, I'm basically making this post to maybe find motivation and give a little more information about the project to anybody who might be curious about it.
I might try to find a pixel artist here soon, but they seem to be few and far between around here unless you're a millionaire. $1 per frame? Anybody want to lend me $100,000?
