Should've Been Fun and Relaxing...
The developers of this game have ZERO respect for the time of their players, and there are a NUMBER of bugs in the game, which made going for 100% rather EXCRUCIATING.
Long story short, if you’re going for both endings, you want to do 2 run throughs of the game: A NO collectible run through, and then a 100% collectible run through.
These levels can be slogs, considering they take 1-2 hours to complete (especially when you're expected to replay them), and especially considering your character’s slow movement speed, even when running.
You get LOCKED OUT of the game’s first ending (the bad ending) if you collect more than 5 Inks, which means, you have to go back through those levels to collect stuff that you want to AVOID collecting the first time around.
A simple workaround could’ve been devised for this: Approach the gate in the hub after clearing all 3 levels for the BAD ending, or approach the Pyramid in the center of the hub (after collecting all Inks) for the GOOD ending, rather than making us replay levels to collect things we should’ve been able to collect the first time around.
Also, you may need to re-collect items you’ve already collected, upon re-entering a level, so if you don’t 100% a level the first time, there’s absolutely NO REASON to collect ANYTHING in a level if you don’t collect EVERYTHING; there’s also a glitch that may void out your collectibles upon entering the 3rd (Forest) level.
There’s also an UNAVOIDABLE location in the Forest level that you HAVE to pass through to finish the level, that glitches out more often than not, CRASHES the game, and MIGHT corrupt your save, making you replay from the beginning.
Otherwise, the platforming is pretty basic (if not braindead) for a 3D platformer, and you don’t get many abilities to play with.
If it WEREN’T for these PROBLEMS, this game would be FIVE STARS, but I’m issuing a Two Star review as a serious caveat emptor for those looking for a stress-free ride, ‘cuz this ain’t it!
