I don't know what the rider is or where is that hand from, but this silly style is just fantastic. The secondary attack... :D You can slap the like button with that. Great thing that the player can shoot out the enemy projectiles. I quite it.
I don't want to judge the movement. I never rod a hand before, so it could be realistic, but it didn't feel snappy.
The animations are great. The hurt hand with the bandages is neat. :)
Oh, yeah. The music. It can stuck into your head. pretty neat.
