First of all, I am at a loss for words on how amazing this launch has gone. Thank you everyone for the kind words, and thank you for the feedback on how to make the game better. I'm really sorry some bugs keep reoccurring, but I'll do my best to fix them over the coming weeks (hopefully days). If a problem keeps popping up and ruining your experience, I wholeheartedly urge you to get a refund, that's why the system is there.
I updated the game to fix the last level where the controller would stop working. However, I am still looking into supporting DualShock 4 controllers, which unfortunately means I will have to redo the entire input manager. Unity's biggest weakness is probably its input system, and that's why you're running into spinning cameras and broken buttons. So for now, the Xbox 360 gamepad on PC is the only official compatible controller for the game. If you're still seeing spinning cameras, make sure all controllers are unplugged and that any virtual joystick or mapping programs are off.
I am looking into the other bugs and hope to fix them soon! Thanks for the help and being awesome! Thanks for the amazing stories you're sending me about how the game made you feel. It's why I do it, seriously.
