I didn't really enjoy this as much as I thought I would, playing through the main quest. Once you finish it, the game opens up into a 'void' challenge which is significantly harder than the (easy) main storyline. I didn't enjoy it. It's not a 'revisit' or 'redo' of the original story line levels, but it focuses more on killing void creatures in thos enviroments, rather than exploring and puzzles.
Main storyline took me 2 hours, and i'm not a big fan of difficult platformers, so I had no interest in what may of been a longer definently more challenging mode. Honestly the controls themselves didn't lend themselves to faster paced more difficult platforming/killing, so even if i was grooving on the idea, i can assure you the controls would of kicked me out just as quickly as the narration.
I feel the narrator was relatively unessesary, and many of the lines of dialogue, i really felt were out of place, or didn't mesh well with the story. Honestly, it's game where the narration should really add to it, but more often than not i felt it pulling me out of the game because of lines i didn't expect or just lines that broke the feeling.
I normally go into this game expecting a big point, or big plot or big overarching theme 'redemption' 'exploration' 'overcoming of one's greif' 'growing up' honestly, I didn't feel any particular ONE theme from this game... and that saddens me because it could of been as enjoyable to me as Thomas was Alive if it had one thing and explored it well, rather than trying to touch on multiple things at once.
Unique mechanics, not particularly engaging though, and marred with questionable narration and thematic choices...
Get it really cheap for 2 hours of entertainment, more if you enjoy the more punishing execution style platformers, but be aware the mechanics themselves don't lend themselves well to the platform genres need of smooth, precise gameplay. It's a game that would of benefited more from a longer storyline or a more crisp singular point, than a second challenge mode and shorter story line. The story failed to buy me in, and so I was left, ultimately disappointed.
