On the left you can see the first and second pass on the boss area, I had originally been going for a classic orange/brown/red theme for the level. I've since changed my mind to a blue/red/orange one. I didn't like the look of the brown tiles and it all felt too traditional anyway. There's a lot of animation work to go into it yet.
The background is due for some pretty big changes. I want the player to be able to see the back of the Volcano as they climb out, but also have desert/mountains behind the outer area. The parallax for that stuff will probably be a real pain in the ass.
A possible enemy design for the area.
Hopefully I'll be putting a new alpha out in this area at the weekend, dependant on how much I can get done.
