Starting positive: Landscapes are gorgeous. The mechanics of parkour and unlocked "powers" are better than I expected, but still jank. Voice acting is great, and the story isn't painfully bad. At no point did anything fail to respond to my input. Giant tortoise. Though I nearly got softlocked once, I never did, and if I had been using the Mark like I was told to then I'd have nothing to worry about. The base-building mechanic feels out-of-place. The epilogue was a bit tedious. Switching planets(?) is a fine mechanic, but it's not clear what actually changes when you do so. Skill tree / economy is poorly balanced. On several occasions, I accidentally pulled myself up through a ceiling. Combat is trivial AND repetitive, a deadly combo. It was hard to see some "double-jump" pads against blue sky/water, and I'm not colourblind.
But my main criticism, and why I'm rating down, is that this is sold as a parkour game but the parkour element isn't quite there. If I didn't know better I'd say this was a different game with wall-running tacked on. By the end of the game, I felt confident in getting around, but had learned to avoid straying from the beaten path, and heaven forbid I landed in water. The choice to have a 'dash' (which doesn't work half the time) rather than a more traditional 'sprint' I think contributed to the general sluggish feeling of the movement. And then there's what I'll generously call a difficulty spike when you switch over to the challenges. There's no way I'm grinding for gold times when simply finishing them seems to require inhuman precision.
