I just played it. I like the background hdma effect but I would tone down the white color a bit. Also the stars are a bit bright and out of place.
You don't need to do use black death block horizontally in a line when you can just use munchers. More aesthetically pleasing.
Contains more than a few kaizo traps in the second half, mainly invisible coin block traps that make it impossible to progress. Not the best thing for a contest.
The message boxes are also littered with profanity. If I were you, I would clean them up. And the first one endorses tide pod consumption which isn't a particularly funny joke.
Overall, design wise, it's definitely a well made level and I enjoyed playing it, but once the kaizo traps started I switched to a tool run. The music is a bit loud, but I don't think you'd be able to change that without picking an entirely new track.
