Please don't submit things that come from tutorials. They count as public files, since you're not actually creating your own game, you're following steps to re-create someone else's game, and so, that's why they're actually against the rules. Submissions must be your own creation.
This wasn't bad, as far as it looks decent and the controls work. But since it's a Stencyl platform tutorial, it might be removed.
If you want feedback and tips, that's fine, but this isn't the best place for this. The Portal is for finished items. The Forums are what you want. Load this into your Dumping Grounds. It's the third icon from the left at the very top of the page when you're signed in. It looks like a bucket with an arrow pointing down. Once it's loaded there, copy and paste the link into the Forums (Community>Forums). That way, people see it and give tips, which is what you want, but it's not in the Portal, which you don't want.
You're on the right track. Keep working at it. Just make it all your own.
Good luck! :)
