The multiplayer, realtime I assume, match 3 is something I haven't seen before so that might even be a real innovation.

The real-time match 3 puzzle idea and theme of light-hearted characters that use spells (and send long garbage blocks to their opponents) seems to be copied from Panel de Pon which was released in 1995.

And adding a multiplayer mode to such games is a must nowadays.

Then there's Puyo Puyo, which is pretty popular online as far as real-time action VS puzzle games go.

For those reasons, I wouldn't really call their idea original...
