So I seen a lot more Windows games that are being TASed thanks to libTAS lately and I feel like this port of a game deserves a TAS spot.
A while ago back in 2017, I found a way to skip Mudomo and Mudanchee for the any% run and Sligfantry found an interesting glitch called the Relocation glitch and later the ARG - Advance Relocation Glitch.
Since then, speedrunner LengaX managed to beat the game in 16:40 RTA. The run was pretty flawless, but with some new time savers found, he did it again to match the in-game time and he got 16:47 RTA which is 7 seconds behind the record.
in-game time being 14:34

Then we also have the 100% category on which we can take advantage on those corrupted wells we can't use in the PSX version and there's already been a sub 2 hour run completed here with minor mistakes:

With the ARG's there a possibility that even more can be skiped and get the time down below a sub 1:40 which would be impressive to see like this Mudanchee level for instance

Also I need to play with the foreign langauge versions as having faster sound bytes might make things move quicker. Like the French version might be the quickest as it might be quicker to say "Salut" or in the Italian version to say "Ciao" than it is to say "Ello" and "Follow me".
