Good Platform Engine?

[Yoshi Boo 118]

I'm looking for an platform engine cause I've been thinking about making a game for some time. Mebbe something that's easy to work with but can be used to make lotsa stuff, but I can work with any that you think are good. So, anyone recommened anything good? I want to get a few options b4 I stick to one engine.

I'm no expert but I'm pretty sure that if you have Flash you have the ability to design your own engine to fit your own taste, which would probably work better than anything else

Or I guess if you're a noob, you can find an engine yourself.
(I don't have any suggestions in particular, however)
