There's no question that Air is one of the most bizarre hacks that would fall into the Total Conversion category. The objective of this hack, IMO, was to see how far the SMB1 engine could be taken, and to exploit things not done in the original game. For example, making getting hit a requirement, making getting X number of coins a requirement, making dying a requirement...all of these things had absolutely never been handled in the original Mario game. It reminds me a little of some concepts present in the Japanese FDS Super Mario Bros. 2 (the one renamed to Lost Levels), such as having a blooper out of the water and reverse warp zones. This hack basically takes these things to the furthest extreme. Now I think it goes without saying that playing this game without an emulator is completely impossible; the whole one-mistake-in-this-impossible-game-and-it's-game-over thing should make that abundantly clear, coupled with the fact that only experimentation and dying many, many times can reveal how the hell this hack's wacky physics fit into a viable solution. Many, many puzzles involve setting things into place so that Mario doesn't get himself killed as he auto-pilots between a flag pole and castle entrance. There's definitely little sense of reality here; Mario should be smart enough to not walk his dumb self into a pit. Unless Air's storyline is some kind of crossover with Lemmings it's certainly little more than the programmer saying "ah-ha! You've fallen into my trap and now Mario will die!" to the player. Remember Seanbaby bitching about the controls in one game, talking about how he always apologized profusely to VG characters he killed off because they misplaced their trust in him for a quarter but would say "It's your fault; I told you to jump" due to this one game's shit controls? This is kind of the reaction you get from playing Air: the programmer is testing the player using Mario and a screwy digital world as a medium, and there's no sense of immersion that you get in a traditional game. Although did anyone else get claustrophobic playing this hack? That being said, I do think that this type of movie does have some merit as a speedrun. In fact, Genisto's run isn't so much a speedrun as it is an "only run." AFAIK, there's almost no deviation possible from Genisto's actions, and for the most part they're done as fast as they can reasonably be, and I'm convinced that the "slower" times are more for aesthetically showing off than actually wasting time (i.e. revealing those hidden coin blocks to show off blocked passages).
