Got another notification on my wishlist that the game is on sale again, bigger discount than last time however it seems the developers have raised the price by a small amount. The game has had some new tracks added to it since last time, however.
The game is a good workout (like Beat Saber) and it can be played on all major VR headsets (including Windows Mixed Reality and Oculus Quest 1/2 via air-link)
My understanding is that this game still doesn't support custom beat maps. Custom soundtracks are possible but the map isn't synced up to third party music. Buying the Steam doesn't entitle you to the Oculus version of the game (not cross-buy)
Do not buy the Soundtrack (Bundle) unless you want the high resolution FLAC copies of the in-game music (they're on Spotify anyway). Buying these will not add any playable content to the game.
One of my most played VR games. The devs seem to be always adding a tonne of new content.
