It's alright
I know this idea is taking from "I wanna be the the guy", and I think you are doing it wrong.
First is the graphics. I know they are not supposed to be good, but since they wanna be the flash game, they should at least look like the other shitty graphics out there. This is just the levels that are bad. The character and stuff is fine, but doesn't fit the no-detail-at-all environment.
Some less important stuff also annoys me, like I can't return to the menu or adjust difficulty. It could really use an easier difficulty level, just for the lazy people.
A major problem is also your collision. I know collision isn't always easy, but it already fails when you first encounter the moving spikes. You can stand like 20 pixels away from those in the ground and still get hit.
You say you intend to have bad collisions and shitty platforms. Remember that IWBTG was supposed to be hard, not bad. I get a feeling your trying to make it look like the opposite.
