Love that concept art! I was brainstorming possible names in the shower for Muffet's "Undying form", and... I couldn't come up with any good ones.
The only thing I could think of was "Muffet the Mastermind" and "Muffet the Merciless", but those sound like villain names instead of heroine names! XD
I came up with one for myself though.
"Ada the Adamant". Now I like that.
Anyway, I have a game recommendation for everyone!

It's an online multiplayer game based off Hearthstone. The two players battle each other, trying to reduce their enemy's SOUL's HP to 0. The players send out monsters, ranging from Froggit to Mettaton NEO to the diamond boys loitering outside the puzzle of Hotland. Monsters have different abilities and stats.
As you play, you gain LV and GOLD which can give you perks such as, for example, a new pack of monster cards.
