It doesn't crash, so much as entirely hang my system. The only way to get it to behave properly is to press CTRL-ALT-DELETE and tell it to sign out. Or toggle the power.

But it has happened to me four times when I kill the second corrupted heart. I don't have it open right now since it just crashed to remember the exact level, but it's Flesh .

I cannot progress right now. I'm going to have to stop playing until this is fixed, because trying to play right now would be pointless as it just crashes on me. It doesn't matter what order I kill them in either, i've never made it past the second heart.

I am enjoying this game, it's just way too buggy. Not sure how this made it production. I know you've heard it a lot recently, but it's true. This game should not have been released when it was. And you should have done PLAYTESTING on Act 2 and Act 3 as it's a buggy mess.
