I also added some better tiles (these were made for another project a while back, though I had to add all the slopes and shades!). There's also a back layer to the tiles, my intention here was to make floating platforms still feel connected to the ground. Usually I don't try to rationalize things that small, but as each level is a single screen I think I can get away with it and it's good screen filler. I added a sun and some clouds (also from an old project of mine, all subject to change!). There's a HUD now too, it's very basic and will function in the same way as Crash Bandicoot does, for example, where you collect apples (here it's acorns) and when you collect enough you get a new life heart. When you collect acorns, they actually fly up to the icon on the interface to be counted.
The squirrel is nearly fully animated, Marc has done a great job on him as well as the other characters/enemies that I haven't quite implemented yet. I'll do a video tomorrow as it's quite late now, however I can manage another screenshot!
