Pros:
+ Metroidvania
+ Good controls
+ Good music

Cons:
- Short
- Too easy. There is 'Nightmare Mode' but it's unlocked until you finish the game.
- Familiars are not different enough. They all do a basic melee attack and a spell, just pick your favorite flavor and don't change it, so it keeps leveling up along with you.
- Orb leveling system. Just like the familiars, they level up as you use them, so you are penalized for changing orbs midway. I ended up using the same orbs for every encounter, just switching necklace or rings as needed.
- Equipment makes little difference, just equip the bigger numbers, also it doesn't show on the character.
- Art: I liked it at the start, but in general the color scheme feels dull and every area felt the same.
- Quests are repetitive: while they flesh out the meh-characters, they usually just consist on looting or killing some enemies, very much mmorpg-style.
- The story themes are very much on your face, sometimes even preachy. At some point I stopped caring.
- Timetravel made no sense (like in many other games), but going about a thousand year into the past and doing some drastic changes, and the result it's just an open door in the future???? can't buy that.
- Timestop mechanic is underutilized, just used to reach few places.
