Other accessible options include Bells & Whistles (aka Pop'n Twinbee) which has just been released as an arcade archives game on Switch, and Vib Ribbon, which was released on PSN for PS3 in all regions iirc. Alien Soldier is on the Sega Mega Drive/Genesis Classics collection on PS4, XBox One or Switch as well.
I've played a decent chunk of these exclusives, and if you can, I'd highly recommend any of the following:
Ufouria: The Saga
Trip World
Alien Soldier
Bishi Bashi Special
Another Code R (This is a sequel to the DS game Trace Memory)
Disaster: Day of Crisis
Kuru Kuru Kururin
Last Window (This is the sequel to Hotel Dusk)
Pokemon Typing Adventure (this is surprisingly fun)
Hammerin' Harry: Ghost Building Company
Jam with the Band
Bubble Bobble (SMS)
