So I just bought this game. I want to play it, but this mode just locks up when I choose my character. None of the buttons work at all and I'm just stuck on that screen until I alt+f4. The challenge mode works fine, though. Any solution to this?

as title

I feel its too difficult. What weapon do you use ? I lost at stage 5. Any tips ?

I have no idea how to beat this mission. It doesn't seem that there is enough time to beat the mission and the boss constantly keeps moving off-screen.

Stream told this game can be played by controler. but I can find "keyboard only" in the setting...
