I first started running Tak: The Great Juju Challenge in 2016 and I believe it would make for a great TAS. The game is filled to the brim with movement tech, exploits, skips and so on. It would take way, way too long to go into absolutely everything in this game, it just has so much stuff that I don't even know where to start. From high jumps to long jumps, from animation cancels to clipping, from skipping large chunks of levels to infinite jumps, this game has a lot. I'll link the current any% WR as of writing this:

A TAS would be able to push the movement in this game to its absolute limits, it can get favourable RNG everywhere and it would be able to exploit the game's co-op much more. In the RTA run, co-op is mainly used to perform drop-in drop-out related strats but a TAS could utilise it much more heavily. The biggest downside with the game as a speedrun however is the proving grounds. They take up over 1/3rd of the run and they are basically just lengthy auto-scrollers. A TAS could heavily playaround in these sections but they are ultimately slow parts of the run that take up a rather significant portion of the run. The game also has an NG+ category where we don't have to play through the proving grounds and we start the game with all the upgrades, leading to faster fights and new strats which cannot be done in any%. I will link the NG+ run as well:

I myself am not experienced enough with TASing to TAS this game, this game is far too complex for my skill set. I don't know if anyone will try and TAS this game, it is a big task for a rather forgotten mid 2000s 3D platformer but if anyone would want to take the plunge, I would be more than happy to help out with strat research.
