Minimum requirements (highest grade = B)

All scenes should include final character and background art. This art should be made by you in Piskel. All features of your game should be "E for everyone" - no graphic violence, no realistic guns/shooting, etc. Please ask me to take a look if you aren't sure if your game qualifies.

Intro

The introductory / title scene should include:

the name of your game
gameplay instructions -- how do you move? jump? etc
credits for music and art (including crediting yourself for what you made)
background music
some kind of "start" mechanism (button, spacebar, mouse click...) to start Level 1

Credits

Credits can be included on your Intro scene or in a secondary scene(s) and should include:

Coded in Stencyl by...
Art made in Piskel by ...
- and/or credit the source if you used someone else's art / image
Music made in __ by ...
- and/or credit your source
Sound effects made in __ by ...
- and/or credit your source

Level 1

Add background music and sound effects. You can also update Level 1 to make it better if you like.

Level 2 (and up)

Create Level 2 of your game (add more levels if you have time!). This should include at a minimum:

movement for at least 1 actor (4-way? 2-way with jumping?)
some kind of interaction between 2 actors (collisions)
harder/different challenge(s) compared to Level 1
background music and sound effects

Win/lose

Make WIN and LOSE scenes so that the player is appropriately awarded for beating the game, or (gently) mocked for losing.

For higher than a B (and a more awesome game)

Add some or all of the following features to your game for more points:

add more levels
add variables to track the score, health / hits, lives, etc
add a behavior to consistently display the level, score, health, etc on each scene
make your own music / sound effects
add a level selector to allow players to skip to the next level (if your game is difficult to play, I strongly recommend this) (can be an easter egg, just tell me how to access it in a comment when you turn in your game)
add an easter egg (tell me how to access it in a comment when you turn in your game)
make an HTML 5 version of your game and/or publish to the Chrome Web Store
do what it takes to bring your awesome game to the OGPC *

*The Oregon Game Project Challenge, or OGPC, is a statewide showcase of games made by high school (and some middle school) students. It happens in April at Western Oregon State University and I would be happy to take a field trip with anyone who is interested. It's a great way to get an idea of what other people your age are creating, and show off what you made! They do have some requrements, including a theme and some online information about your game.
