Controls are a bit wonky, Most of the time I input a certain attack it doesn't come out. (The uppercut especially, There is a reason smash Bros has a designated jump button instead of up as the default.)

and the enemies in the single player levels are very tanky. The Counter doesn't seem to work, or the timing literally frame perfect. I activate it, the attack hits me, and I still take damage. 

BUT  I had fun messing around with it. It certainly does what it intends to do, which is just be dumb fun with friends.
