Connecting blocks to activate different buffs and debuffs is a lot of fun! I liked the platforming systems you had in place, like wall-jumping. I think it would be cool if the buffs/debuffs were a little more essential, I was able to beat the sorcerer without using any. Maybe that's just a challenge mode ;).
If you made a 4-player couch coop fighting game out of this I would pay 20 bucks for it, no question. Nice work!
