1st level - Too many swamp tiles and they are also placed very badly.
I don't really like the way the path changes from on style to the next, I prefer to stick to the one style in the same level.
2nd level - Like the others said the houses are nice.
Although the one on the right, the grey path tiles, there are a little too many square-ish tiles. The grass detailing could use a little work too but it isn't bad.
3rd level - Swamp tiling again.
The house again is great. You shouldn't use those small brown dirt tiles, they are blockable tiles, don't know why though Stefan should change it.
Grass detailing again is okay but I prefer it a bit more jungle-ier (damn 2k1
) but the grass gives it a closer to classic feel which is a good thing too.
