Rez Infinite is a modern remake of the game Rez, originally on Playstation 2 and Dreamcast. Rez is about a hacker breaking through firewalls in cyberspace to reach a malfunctioning AI. The gameplay involves flying your character through cyberspace and targeting multiple AI defenses at once to chain your attacks.

The game was big on rhythm and synesthesia. So the game is trying to get you basically into a trance. And as you play, your character transcends forms the longer you last, with each form gaining more detail:

Each time you die you start out at level 1. If you get hit, you go down to level 0. So you have to level up multiple times and not get hit to see any of the later forms. I’ve never made it beyond the level 3 form.

Another weird thing about the original game was, in an attempt to really push for synesthesia, the game came with a “Trance Vibrator” which you could plug into the console to further enhance the haptic feedback on the controller. It was a vibrator. Even the game creator admitted it could be used for sexual stimulation. I don’t know how they actually got that manufactured and claimed it was for anything else.

Here’s a trailer. You can play it on Steam, Playstation, and Xbox. And it has VR support.

Also, the creator made a spiritual successor called Child of Eden but I’ve never played it.
