Identify of cell sport, grid tower defence like

I used to play this cell sport, kinda tower defence like on a grid

The items you used have been like a soldier, mage, archer, within the form of teris items, and every bit's background was frivolously colored. Hooked up is an impressive drawing to indicate what I imply

The taking part in subject wasn't at all times sq. in form, and the best way you positioned your models can be how the enemy would transfer throughout the board, create a path

Waves would come via, and you may add new items on the sphere after every wave, from what I can recall

For the lifetime of me, I can not recall the identify and have been desirous to play it

Thanks! ^_^
