The Revive mash thing definitely doesn't work for me, tried it again. The bpm maxes at 70-ish and then plummets to usually 35 even though I'm mashing as hard as possible. Then it's at 0 when you're supposed to push RT, and then fails. 1/10 times it succeeds due to some bug where I mash all the buttons on the controller as I'm holding RT down.
But I don't mind too much as it adds a layer of challenge; don't die. Going Very Hard on my first playthrough might not have been the best choice, but it's quite fun.
Lovin the game, it's Suda through and through, in glorious 1080p/ 60fps.
At what point do you get the ability to do this in the game? I've already beat Mission 4 and have yet to run into it. I just use the heal ability by exchanging blood for health.
