Dunno about a name for this character, but here's how it goes
The character is a puzzle one, and collects blocks like the others
It's power is to halt matches, on right click, such as, say you have 6 blocks of same colour about to leave the board, you activate the power and the match holds for 5s, allowing you to bridge gaps, and collect more blocks, making a bigger match and not loosing your chain. Though the draw back is unlike normally, when you overfill a lane with a match, where the match leaves the board, when match hold is on, the board acts like there isn't a match and overfills, causing loss of score and respawn. As with this character the higher matches are possible, such as m21, each match is worth 20% less, meaning to compete with the other characters you need to attain this. Though to beat the other characters when they have m21, this characters ability to keep a continuous chain through out the track will need to be utilised.
The power will have a recharge time to it of a set amount after the match has left the board, or after an overfill, so no continuous use.
