I'll do that, sure. By 250x, you mean 250px wide? Is there any height requirement? On second though, I guess I can check that when I download the Monster Game.
I also just got out of school so if you need any assistance at all, just holler. I'm sure there are plenty of people who would be more than willing to contribute, myself included.
I could make more sprites in the style I was doing (probably without shading, but like almyki said, that can be done later...) if you'd like. I wish I could make some generic tiles to go with them but I'm not good with tiles (funny, how I'm also bad at drawing scenery and terrain, I guess they are connected somehow)
Sure! It isn't necessary at the moment, but I suppose at some point we will have to consider more original placeholder graphics.
