Nice game and idea, I enjoyed it!
Some criticisms I had:
- Cannot read signs while holding shiny
- Sometimes vines will get stuck and I have to restart (in earlier levels)
- The last few levels were very finicky (especially 'Oiler') and I had to retry many times, because it was very hard to use the shinies to manipulate the vines how I wanted, very often I would try to "rush" a shiny past a vine I didn't want to move, but the vine would still catch the shiny and move just a little bit which was enough to mess up the flow of water. Also I would sometimes lose the shiny if I moved it at a very high speed, because it would get caught in some terrain, which was very annoying in the last few levels.
