You had me when it was a PolyBridge clone :-) Interesting inflate mechanics, they definitely add something to the puzzles provided (except the joints at the bottom, which I straight up skipped and built top only). Do you have more mechanics stored up for a post-jam version?
Obviously this is a game jam version, but Copy/Paste, deleting segments and adjusting segment angles (with Shift click muscle memory from Poly, rip my bridge - it gets deleted every time I try that) would be my top QoL improvements to add. Good work!
