This is a Stencyl tutorial. Don't submit whatever comes out of a tutorial. Many people do that, so this is already on here. Do you know how many times this has been put up already? Here's a clue:

Which looks looks just like this one: http://www.newgrounds.com/portal/view /592450
Or this: http://www.newgrounds.com/portal/view /594051
And almost like this one: http://www.newgrounds.com/portal/view /590439
Or this one: http://www.newgrounds.com/portal/view /593630
But at least this guy changed colors: http://www.newgrounds.com/portal/view /592752
Don't feel bad. It's a typical noob mistake, even though you've submitted all sorts of 'stuff' already. Hopefully, though, this review will help you to realize what goes on around here. People get Stencyl or The Games Factory 2 and they do a tutorial and they decide to submit what they created. The problem is that 75 other people have done the same tutorial within the last month, so 74 versions of the same game came thru. (One person had the sense to hold out.) If the game works 100%, then it helps, but more often than not, the tutorial produces a game that isn't 100% functional.
Listen to what people say in their reviews. They'll offer tips to help improve (well, some will). For this game, I'd suggest changing the jump button. If you're going to have arrow keys for movement, have an arrow key for jump as well.
Hope this helps.
