many people report that controller support no longer works can some one confirm if controllers work now or not

In this mode there is a bug. The enemy can be outside the screen. And then it's impossible to kill him. He doesn't want to go out and reach it does not work. This bug is reproduced randomly, but very disturbing. Video describing the problem ...

其实我想知道最后一个收集物是什么？成就好像也没体现出来，难道是任务一那个成就？并不知道怎么完成。。。

But i dont understand why when i die appear other character. I prefer have more lives when i die or repeat the level with the same character. Could you add an option to die when die the main character. Sorry for my english. Thanks for this huge game.

I'm now on stage 4-2. Whenever I die the game is stuck on the white loading screen and the only option is to restart the game. Ubuntu 16.04
