I gave up on doing achievements (was trying before) because the game/my game somehow bugged and did not count my new game plus towards achievements (it says that cheat/easy mode was enabled thus disabling achievements, despite the fact that I did not change difficulty, nor used cheats). This was after I completed Path C so that was an extremely disappointing aspect.Up until I started trying to do the Achievements, this game was pretty fun. I screwed myself by trying to finish Path C (save Uno) while also playing just an Adventurer, and I'm absolutely sure it's impossible.
Path C is orders of magnitude harder than A or B, so beware.
