Hey, there isn't many guides but the normal campaign there isn't any missable I don't believe (I've got all trophies bar Roguelite) The only issue is the Rogue Lite mode, the game constantly crashes so its near impossible to finish this mode. I reached out to the developers who apologised and said they'd pass on to the people who ported the game (Jandusoft) but I can't imagine anything will change this late down the line
