Ok, since I don't know much about programming (except for logic), I decided to use Stencyl until a programmer shows up for this platformer I have in mind. However I'm having these problems:
1) My tiles are 16x16 but I have some tiles that are beyond that (20x16 tiles or 16x20 to make them less square-like), how do I get this to work? I tried to separate the extra bits as a different tile and remove collision but it becomes a part of the background (tiles are behind the actors for some reason). Is there a way to place tiles or even other miscellaneous objects in the foreground?
2) I'm having trouble coding the jump

Animation Sequence:
Starting (1 frame on the ground, .2 secs)
Rising (1 looping frame in air until it hits the peak of its arc/jump)
Peak (1 frame at the peak of the arc/jump, .2 secs)
Falling (1 looping frame in air until it hits the ground)
Landing (1 frame on the ground, .2 secs)
How do I get this to work? I'm also having trouble with the facing right facing left situation.. Here are my current events for it:
Running (made this myself very proud of it)

Jumping

Facing Directions

Landing

Sorry if the logic is flawed. It's my first time to use this.
