My kids are playing it atm before school. No new games unlocked yet, boxing is a hit. Ah there it goes, you unlocked all the games! Will find out later, they're playing something with clowns now...

Ok, initial impressions for the ball count, cow milking, shaving and safe cracking.

Yes it works, no it's not all that impressive. It feels like the small rumble motor in dualshock controllers going at high speed (fine vibrations) except it's able to stop and start quickly to provide a click like sensation and mix different speeds for varying results. It doesn't feel like balls rolling around though. Only shaving is closest to what a foil shaver feels like with a bit of imagination.

The controllers don't seem to be able to do heavy vibrations at all, too small probably. Perhaps with both of them in the grip it can make some more complex vibrations, separated in 1-2 switch it's kinda meh, not worth $50 for the game nor $70 for a controller. Expensive tech demo for underwhelming tech, luckily my kids like the game. Perhaps some of the other games make better use of it, yet I only had time to try those 4 briefly.
