To polish and publish your game we need the .gmk file, all the art work, sounds, and other files used. Preferably you should own the copyright for all the material you uses. If you are using anyone elses material, ensure you have written permission from the author (we will need a copy of this agreement). If you do not have the copyright of certain material make this very clear. We will then have to create new version of those assets. (But as this will cost additional time and money we will only do this if it is a really excellent game.) Any game created with our own assets (graphics/sounds that came with Game Maker) are also okay, as long as you tell us. We recommend that you author your artwork in iPad (or higher) resolution and shrink for the appropriate target. In that way it is easy to produce the game for both platforms. The more you can provide, the more control you'll have as to the final look and feel. So if you don't provide usable assets (like icons, original music etc.), we will have to make them ourselves, although this may cost you if we have to commission art/music.
We also need some specific images that are used to promote the game, for use in Game Center, etc. Preferably provide them yourself, if you want control over them. These are not IN GAME assets, but assets requred for web sites and promotion.
Achievement icons authored at 512x512 (required for Game Center)
Game Icons at 57x57, 72x72, 114x114 and 512x512 in png format.
Game Logos authored at 1024x768 at least!!
This is under the "Assets we Require" section. I've struck through alot of it as me and the team have taken it all into account. But the unstruck stuff I don't quite understand.
-Assuming Achievements icons are for achievements, do you need to provide icons if you have no intention of having achievements in the game?
-What's the Game Center?
-Why does Game Logos have to be of at least 1024x768?
