I've made a bit more progress with this, so I thought I'd resurrect this thread.



I added a background to the swamp level. The blocky look doesn't quite fit with the detailed background, but I think adding more tiles (corners, etc) might solve that problem. Also added a miniboss.

And these are the sand desert tiles so far. My buzzards are purple.

The sand desert level is going to have the same problem as the rocky desert and snow level with how bright the tiles are. I'm happy with how the swamp level turned out since it has darker tiles, but I'm not sure brightening the sky more in the other levels would work very well without outlines to separate foreground from background, or a less limited palette. I figured I'd just stick with what I have now since I might have a chance of finishing something for once. It's good practice in any case.

Here's a boss and a few minibosses.
What do you think?
