Wow, at first, I gotta say, I was kinda hesitant about downloading this level, but, for a first level, this is pretty good!
The dialogue had a few typos and the story was a bit emotionless when it felt it should have had some emotion, but the tilesets were nicely picked, the level, save for a few SGEs, or "small graphical errors", like having a ground tile placed where there's no black border around it because you wanted a one tile wide platform but the tileset doesn't have that.
There was also a part where, after the meteor, some corner pipes weren't connected to anything. I assume this was to simulate the pipes being broken, but when they're cut off perfectly like that, it kind of looks funny. :/
Other than that, it was a beautiful level! I love the gradient you used and the way you flowed from the canyon tileset to the forest tileset. The clouds were nice, too! I wouldn't have thought they would work out that well. :P
Seriously, gaiz, download this. You will not be dissapoint.
