Thanks for playing! I wholeheartedly agree about the movement feeling clunky. You can definitely tell that it was the most basic system I could come up with to let the player move around. I especially agree with the hook,since the functionality should be straightforward, but in practice it feels super inconsistent and frustrating. I appreciate the brutal honesty because it doesn't matter how good the tech in a game is if it isn't a good game.
I like that you point out what parts of the gameplay drew you in, like the swinging, falling into water, or heading towards a landmark of some kind. I'll definitely build that up in future versions. More gadgets are definitely a priority, and I like the X-ray idea. A similar item I had in mind was a 3D sonar (inspired by Little Echo!) that could give you hints about the terrain around you. Another idea is a pair of climbing picks that would let you scale steep or concave walls.
TBH it was a little too ambitious to make a fun demo in 1.5 months of dev time considering I didn't have a specific gameplay loop in mind
