Overall pretty fun, fluid and to the point.
Only issue/bug found is that some stats like Attack Speed seems to not reset on consecutive runs (at least right after winning)
Also, the victory screen bgm makes it absolutely worth it.
Great game, 100% completed after about 12 hours on my first playthrough. The puzzles and riddles are very well thought with a nice presentation through ingame screenshots and landmarks.
If I were to remark a possible issue, would be the lack of 'Fast travel' options, especially at the second area during mid game.
Overall is a solid 9/10 for me.
