Yes they are, I was worried it wouldn't be readable at that size and with only one colour. But my main worry was readability of the whole scene, like if the player knew what was in the background or the forground.

 Well I was happy with any high saturated colour, my twin wanted this.

 I know right. If I could, I'd use cyan for a background. I'm not really content with one screen either, but at the moment the challenge doesn't allow for it.

Doh, this is a restricted challenge.

 looks cool, those thigies are spiders?

This was totally gonna be my color scheme, but I saw you already did it in the forums, had to settle for green. Yours came out really nice =]

Oh come on, add a few more colors. Make the player char cyan, and the enemies chartreuse.

I'm waiting . . .
