I don't konw how to give a good suggestion with my broke english.The only i can do is discribe the problem that i've met.
Frist, i change the gunmode at keyboard "x" to "v", but it didn't works. Second, sometime the skill can not works, but you can change T-doll to fix it (But sometime you can't even change T-doll lol). And i can't start a newgame after i finish the demo. Also i can fire in guncustm just press "r", in TPS mode this situation made my finger bend back.
But it is still worth an experience. I'm looking forward to future updates, Keep going.
