I also play Beat Saber several times a week! It’s loads of fun. I find the multiplayer gets me competitive and I’ll end up playing for up to 2 hours (assuming I’ve kept my endurance up).
I’ve never seen that replay feature before, that’s really cool. I stopped playing modded songs a while ago because the plugin kept breaking and was incompatible with multiplayer. Has that gotten any better? (I play on SteamVR w/ Valve Index)
