I think the main issue with self damage as a deterrent in ErthTk is self dm's, but I didn't experience any in this mod because of the higher dmt. That may be because I was careful to avoid it, but I'm also careful to avoid self dm's in ErthTk - and I certainly still do it in that mod. Of course points are a factor, but it doesn't take a lot of care to avoid the point side of self damage in general, where in ErthTk unexpected self dm's do happen sometimes. I think it's good to have self damage to encourage cleaner movement and avoid weird tangles - one of the reasons I enjoy ErthTk. No goatses in tk please lol.
I had fun playing the mod a few days ago. What i liked most was that it emphasises the improv aspect of tk, where the latter half of the match can be the most important moments and it's not all about the opener, encouraging good improvisation to win instead of relying only on a snapkick or only on grab-defense openers (pick your flavour).
It's a fresh take on tk and I think it has a lot of potential for competition. I look forward to watching and participating in any future tourneys hosted with it.
