positives:
-it's more "hardcore" than the previous one, since for plot reason, in the main city you cannot rewind as you please (instead there are "check point" system hidden troughout the city) (some example, there are rewind system similar to majora's mask. if you "rewind" everything you do will be undone, but you will retain items, knowledge, clues. NPC wont remember their encounter with you, but you will remember, both your character and your meta knowledge)
-it is part of the strategy on how you play the game too. for example, if you get killed by guards, or get trapped then rewind, there will be a new dialogue choice on evading those guards or trap)
-overall, it is the same experience as the previous ones, but some improvements, for example the counter spells plays a big role in this one.
-mampang is a great, memorable setting with alot of secrets to find. also probably the least linear one. (the games aren't exactly linear, but this feels the most free out of 4)
-endings are satisfying, and ALOT, i mean ALOT like TONS of ways to defeat the final boss (some of it even affected by your decisions in book 2 or 3, especially 3) aside from what i did, i figured out 2-3 more strategy to defeat the final boss, and even a super-hard to find
negatives:
-no free rewind can also be frustrating since everyone forget what you do. if you need someone's help, you have to talk and navigate trough dialouge over and over again everytime you rewind.
-it also VERY ABUSEABLE. duplicates everywhere. since you retain your items every reset, you can go back in time, buy/loot the same thing over and over again. i have like 5 sun jewels and alot of magical artifacts.
-the same thign apply for money. there are gambling place where you can obtain alot of money. because resetting retain your stuff, you don't have to worry about money cos you can always go back and play swindlestones and earn tons of coins
