Advice for my first game? [RESOLVED]

Me and my friend are ready to make some games, but I want to get the hang of the coding interface first by making my own simple shooter. However, I want to add something creative to it to challenge my amateur-ability to code. Can anyone challenge me with some crazy idea that is NOT already available as a behavior on StencylForge? I'm feeling confident. 

Create a behavior that allows the user to customize the game [actors, backgrounds etc] to an extent.
i.e a bit like scribblenauts. ^_^

You asked for a challenge

That's a little more art-based than code-based.

Actually, the suggestion is more pure code. Lol.

Anyways, you can search up random shooter games on Kongregate or Newgrounds and just copy anything in the game that you find particularly cool and achievable. You are here to experiment and get used to Stencyl after all.

Ok, how about the ability to go back in time when you die, like in the game "Braid"

Fun fact, i actually thought of making something like braid. My idea was that each actor would store a path in a list which he would follow when the time would go in reverse therefore giving the illusion that time is reversing.

For some reason my fps was dropping too much though even though the list was fixed ( 300 elements each i believe? ).

That's a little more art-based than code-based.

incorrect. although there would be an artistic edge to it, yes.

Hmm. What method/code did you use, exactly?

After taking up dtrungle's advice of using ideas from another flash game, I have decided to implement something like Time Fcuk in which you switch between two worlds. However, I would like to thank everyone else for THEIR suggestions! ^_^

I dont even remember tbh xD. Was some time ago. I think it was the follow path behavior from the forge.
