Since I've worked sum on Ekaiyo, I didn't have time to code for this project. I did however, create a full grass-dirt tileset, and am adding walls now. They lack distinguishable borders, but still they're better than whatever I created up till now (clicky here for pictures).
Will finish polishing (or rather destroying ;) ) the walls, and resume working on level random generation. I really don't want to have to fall back to hand-created levels.
