Really interesting idea and great graphics (surprised at how smoothly it runs in browser!) but could definitely use some polish to release its own potential.
I like the idea of having an obstacle pinned to your own body, but I would really like to see smart usage of it to also get trickshots - like levering yourself to get really high or something. I also wish there was less startup momentum and inertia overall so it would be easier to be precise, might be personal preference but that would help a lot with the platforming as I spent more time fighting the controls and positioning rather than the level design.
Really cool project though and I'd love to see it get expanded.
