Well, the bar that says when an enemy is about to do something got stuck on the screen even after the enemy was killed. On tier 2 part 3 one of the enemies were still alive when I won the round. I just got counter attacked by a reploid guard which did "nan" damage. Turns out that gives an instant kill. Also upon leaving the arena to get my health back, I will then randomely get the arena background come to the front and block my vision, like when looking at my menu outside of the arena, losing in the arena or escaping in the arena. I've been playing for quite a while now and that last bug has forced me to repeatedly close the game and reopen it. It's taking out all of the fun.
And there's also tonnes of typos, far too many to mention.
But like chapter 1, it is a fun a great game. I am still awaiting chapter 2.
