Hate to burst your bubble, but 2D platformers are well oversaturated, so unless you come up with a really unique take on the genre, you'll be one of many. If you want to make this for fun, then go right ahead. But if you want to make it for the money, I think you need to really think about your genre.
Hmm....isn't that the case with every genre these days? For every platformer there's a top down RPG, then for every RPG there's Rouge like. There seems to be more to a games success than it's genre.
What I'm noticing is that the art style is what seems to make or break games if they're going for profit.
Look at games like Cup-Head....Nothing revolutionary about the game play, it's a Platformer - Shoot'um up... most of us yawn at that alone....but it's art style is what sets it apart, and makes it a success.
I do not care if it is oversaturated. I have confidence that it is possible to make success happen regardless. There is still a market for platformers, and it has it's fans. I will try my best.
Have you gotten any responses? Maybe telling people what the games about would inspire/paint a picture?
