First Level in a while

[Vega001]

You have a lot of empty space. You can occupy this space by increasing the grave area, adding more trees, or adding swamp grass, water, or dirt.

As a single level, the level is unbalanced because of the trees on the left and top of the level. If you were linking this level to others, it might not be a problem (particularly on the right side of the level). As a stand-alone level, you may want to consider adding trees to the right side of the level.

Tigairius's suggestion of varying the placement of the graves is an excellent one. I would also recommend spacing them out (at least vertically) a bit more to provide more space and ease of movement for players.

Lastly, I would recommend you shrink the top middle portion of the roof of your building by one tile horizontally from the right in order for it to line up with the rest of the roof and building.
