HOLY SHITTING CHRIST BATMAN! NEW SCREENSHOT!
This shows the third and final environment, set amongst rolling farmland, which confusingly will probably be the first used in-game, with the forest second and beach last. Unless I end up using forest first and this one second. I'm not sure yet. To add variety each environment has three time periods - day, night and sunset, and the sky, lighting and ambient sounds will change accordingly.
You'll no doubt also have noticed the big circular saw blades to the left and right of Jack. When the game's eventually released you may want to avoid touching these.
Right! Time to design some levels!
