Giving it a bit of testing I definitely really like the fading fist, its a much needed movement tool for lily and orbit considering i've noticed they tend to struggle approaching (then again I forget dash attacks exist half the time cus I play totem most lol). As far as the yellow crystal kick is concerned I did actually find it useful, specifically for mixing up on shield, as the opponent might drop it or use the crouch attack after they would expect the standard crystal to hit, but get caught by the delayed window of the variant (bots especially fell for this). so while not exactly a great move I did find use in the moveset.
Thank you for the response, and ill make sure to give feedback on any future updates the game has to offer to give you a better audience perspective :)
Edit: I found a funky bug (I suppose) where if you are in training and manage to get your opponents hp to zero (I found it easiest to either spam the lily up attack while using orbit when available or the totem monster crouch attack, both while using the wall to keep the other player close) Every hit done at zero hp will do the "finishing hit slowmo" effect that normally happens, which leads to comical results when using multihits, this probably won't realistically effect gameplay but its worth mentioning.
