Here is my level (built by levelengine) that I've sent in to the Make A Good Level contest, which was done for two reasons: To win and increase my credibility as a level designer and to make sure that Raocow himself knows that I'm good at this.
I got a music track (the track that you hear throughout the level), some GFX and a custom sprite (the pot, which caused the whole angle towards the part that requires patience). The music track instilled a feeling of fear and darkness inside of me, so that's the direction this level had headed in. Besides, I thought that a level like that could look good, so I went ahead with it. I wasn't and am sill not sure if the GFX was for the custom sprite, so I made my own to use with it. I also thought that if it were too hard, it wouldn't be enjoyable, but REGARDLESS of what I would have done, this level would have STILL been easier than the one made by Jolpengammler or the one made by BlackEscargot.
