If I had to guess he didnt want to end things too soon, tried to put in stuff that didnt end well and now it would need too much work to make a somewhat fitting end. I wouldnt call it shitty cause of that. Read the reviews and you will find manny did enjoy it (up to a certain point). So yeah, current last parts are messed up. Then again if he would take the time to may rewite some stuff and introduce a proper ending it could be saved (very low chance, may not impossible, but for sure not this year
). Still I've seen a lot worse, games years old and 3 pages here (rightly so).
