I just tried this game out, it's very cool. Kids would love it for short bursts, but I expect it would be far more popular if it had multiplayer. I understand it's not on the roadmap since it's just one guy developing it, but I hope it's successful enough to add one day.
Also it would be better for arcade use if the vive grip buttons weren't necessary, just use the trigger as a grabbing toggle
