I love clever puzzle games like these, usually, but I didn't find myself falling in love with this one. Don't get me wrong, the idea is great, the art and music are cute, and the game as a whole was very well-polished. But I found myself to be frustrated more than I was solving puzzles.
For starters, the control scheme was really clunky to use (imo, I see others didn't have an issue with it). Maybe I was just using them wrong, but I much more would've preferred E to be pick-up and Shift to be rewind (and rope just to be on the left click). I ended up losing whatever block I was tugging more than I care to admit because I pressed the wrong button and picked up the coil instead (breaking the rope).
Additionally, I didn't like how ropes just kinda snapped even though they didn't seem to be under any stress yet (still dangling), or how they disconnected automatically when reaching the coil. That also made me lose the block I was tugging more than I care to admit.
The player blocking the connection for ropes was also less than enjoyable, especially because it's pretty hard to move only slightly (especially on slopes). I'd regularly just move out of the coil's range entirely on accident, which was less than ideal.
All that combined, just kinda made me quit out of annoyance in the middle of stage 6 (sorry). But I suppose that's a fault of my own, not of the game's.
Don't let my comments discredit the work you did, though. I liked what you put together and I liked playing the first 5 levels (...for the most part). Excellent work!
