That list is crazy, so many niche platforms and limited availability:
- Glitch was a failed Flash based MMO, that launched as a production release, was pulled back into beta 2 months later and then closed in late 2012. During this second beta they seemed to host a virtual death cult. Its messaging framework was later rebranded as Slack
- Tenya Wanya Teens was designed to tour as an art piece last exhibited in 2014
- Alphabet was bundled with Experimental Game Pack 01, a promo for LA Game Space a failed incubator/exhibition space the broke up in 2018
- Woorld was a mixed reality game developed for Google Tango, a tech that hasn’t seen support on a new device since 2017
- Crankin’s Time Travel Adventure was developed for the Playdate and was featured in Season 1. This is still available, in fact it is a pack-in title with the Playdate.
I’ve just wish listed Wattam, its his only still available non-Katamari title that runs on a mainstream platform.
OFLC have pulled the page listing it as RC.

The pulled page indicates it was an IARC classification i.e. it was automatically classified based an Konami’s answers to a generic survey distributed to classification boards globally. If Konami contest the automatic classification then it will be looked at by actual humans who may determine that offensive content is contextualized to a degree that it can be released (or failing that give a list of content that needs to be modified).
