I liked the mod and I played with it a lot, so I can say that it's addictive. I came here to report some bugs I found, if they haven't been fixed yet. I think this would be helpful.
One very notable thing is that if you get a life with infinite lives, you only get 30 rings, but if you kick a life monitor together with another monitor (I don't know if it's exactly just with the ring one) the rings are scammed and you get 100.
Another bug is that if you are playing in multiplayer and do that super standing pose by pressing toss flag and someone completes the level after you use that taunt, you detransform and stay in the XSonic edge pose in the base form, I don't I know if this was supposed to happen and that's why I'm puttin' it here.
Another very notable bug is that if you use Ring Burst in the special multiplayer stages, the rings you picked up start to increase again as you use the skill, and doing so makes it impossible to get a perfect bonus in the special stage.
Lastly, if you have the XSonic's custom hud and another player in multiplayer has their custom hud disabled, and you spectate them in the viewpoint, that person's hud simply becomes invisible to you, and if that person spectates you with the hud disabled and you with the custom hud, it visualizes you with the vanilla hud and the custom hud together.
