I took a look at the first level, and it's...sorta fun to watch, I guess. Obviously it'll become much more interesting to see you clear the later level's puzzles at a breakneck-exciting speed, and Ex. 3 should be tons of fun to watch to completion at that sort of speed...but I can't help but wonder how exciting this really is. Don't get me wrong, it's not bad, but the fun thing about a TAS is using any exploit possible to glitch through the game in just mere hours, with mechanical-like prescision. In games that have the potential for things like wall clipping, skipping certain story events, or simply exploiting the games physics to run faster, that's usually a hoot, though this game is just really built solidly, and I'm not aware of all that many ways to exploit it with the frames, if any. Basically, it just looks like you're playing the game normally...while not stopping, of course.
I'm probably being way too picky about this, especially for someone who only watched the first level of gameplay, though I figure the more challenging spots will look exciting when done in complete succession. Just saying, if you're not going to be rapidly-exploiting glitches that require tight 1-frame timing in quick succesion, it might be easier to just do a regular speedrun. Or maybe it would be harder, but more rewarding? I dunno.
