Very well, then.
Easy: List the number of objects placeable in the KS editor. "Null" objects (such as object 0 in every bank) and the custom objects don't count.
Medium: Make a GIF animation of an exploding shoe that is at least 16 frames.
Hard: Find a completely free audio player that works on Ubuntu Linux (yes, the latest version) and has accurate playback of the following formats: .it, .mod, .mtm, .psm, .s3m, and .xm. I don't care about the rest. (And yes, if it works on "Linux," it's pretty much guaranteed to work on Ubuntu, but I specified that for the sake of completeness.)
(I hope it's allowable to use this game to get people to do things for your own convenience
