I hate to bring more bad news, but...
it seems the left stick doesn't work what so ever, I can use the right stick to look around, but I need to walk sing the D-Pad, even though is 2D and that feels better, my finger hurts playing for too long, and even more during the escape / struggle scenes
also, the B button doesn't do anything in gameplay, you could use it to swap between Ice bean and curly bean (I don't know the name(
a minor bug that I also found, is that when you find a new bean for the gun, it won't appear in the menu until you leave the area
