[4] Irisu Syndrome
It's a cute little anime-ish puzzle-ish arcade-ish game from a long time ago. It has a cult following among /jp/-adjacent people. Surprisingly, it does have a story, and with a very unique atmosphere to it. If you're the sort of faggot who likes Yume Nikki spinoffs, plays obscure VNs and had at some point installed Digital Witch Mayura on your desktop, well, you've probably already played this and are annoyed at me talking about it like some unknown thing. But on the off chance that you haven't, you should give it a go.
