Hey again! Finally managed to beat the robot (and thus the game), and I have a few more suggestions.
Firstly, while I agree with a lot of what gruevy said, I would disagree about the camera speed... kinda. The problem is that while the camera is indeed a bit too slow to turn after wall run turn, it's also too responsive for very fine adjustments (such as when you're trying to line up a jump along a narrow walkway). (Not sure if this would be as much of a problem using a controller, but it definitely is for a keyboard.) One thing I considered was having the camera auto-rotate after a successful wall run turn, but that might just end up being too disorienting for players who've otherwise had far more camera control.
Also, the first wall run turn puzzle feels a little broken to me. With ever other parkour puzzle (including the second wall run turn puzzle), I know exactly what I'm supposed to be doing. With the first wall run turn puzzle, all I can do coming out of the turn is launch Tikal at the platform to the right and hope he makes it. Sometimes he climbs up to the platform; sometimes he wall runs up to the platform. One time he even went through the middle and ended up on the next ledge along (I have no idea how, and also that meant that I'd missed the checkpoint, so had to do the whole thing again at the next death). It just feels like there should either be a ledge at wall-running height to just drop onto, or a climbable wall at the end that can just be run into.
Regarding fighting, one of the tips said that you can stun your enemies after three consecutive hits, and it would be nice to have some kind of visual signifier of this (e.g. cartoon stars over their heads), because I have definitely managed three consecutive hits against the pigwolves and they just look like they're still fighting.
On another note, I really liked the final cutscene, although I was a little disappointed that Tikal changed back to the default outfit for it. Also, in my game, Tikal had almost died facing the robot, and his "I'm hurt" noises were still audible after the cutscene had finished.
Thanks for reading! Good luck with the rest of the game!
