Yo, a friend and I made a discord server for the game. Although not approved by the devs, it should be a nice social hub for people who are still active. Check it out: https://discord.gg/AQBpDFUSZ2

To my knowledge, yeah. The game can be kinda broken at times if you play for long enough, which can be really frustrating, but it's still an all time favorite for me.

They're completely random. You can test it by slashing him before he completes his own slash. He'll parry it then double back and either go for another hit, or shoot at you/do the triple slash. Each triple slash will generally have a pre-determined distance but he'll always try and predict where YOU'RE going to go.
