A friend showed me this but I can't play it on my own – Battle Knife: Online PvP Review

At first, a friend showed me this game, and it was fun, and I wanted to play it. But now that I have it, I can't eve play the game! Any time I try to get into a match or it's about to start, the game crashes and I'm sent to the homescreen. On a side note, I don't really like the fact that you need facebook or have a facebook account to backup your save. Please make an update that fixes the crashes and the sign-in stuff would be great. It's a great game, and it has potential.
