Good job for a small level! It seems hard, but there are a few areas where you can speed through the process of the level. Thats good. Some background lines would be nice, therefore, the level would look really nice. :)
I saw your comment on the left, this level is not accepted. It's to be edited. Just click on the EDIT button.
Also try to capture a better thumbnail (hold down the SHIFT kay while capturing in TEST mode).
