You should add some Platforms and do something against the blue sides then it would be perfect

I just played your stage and must say its really cool, its simple but still very very nice to play on   
one of my favourites <3


Also i made 2 Icons for this map since I want to have Icons for everything I have added :3

Here is the Icon Next to the Stagename


and here its the Logo Of the Game it belongs too

The secound one was really hard work

Feel free to add them to your map.rar but please leave a small credit for me if so
