The game isn't pokemon. If you can find me a modern tileset that's as good looking as the pokemon ones, I'll take it!
So these are four maps stung together, and the one with the building is with the main characters, excluding the guard.
These maps are set in a dense forest with a large lake, where a government military research facility is located.
The research lab has yet to be finished, so these are just the preceding four maps. The first two are supposed to be on the other side of the lake, so they don't tile well.
