I would nearly call this one “easy”, as I never got stuck. I like the way you have to consider once the bulbs, once the loop… and once both in the same time. Nothing tough, but some interesting deductions to make.

Very interesting indeed.
Loved the way how the loop satisfies the 1Up at R6C7.

This is definitely the hybrid I’m most excited about. Doesn’t it just feel like these forms were meant to be together?

Maybe to the solver it does, but they were kicking and screaming the whole time. 😦

how would you make a large one of this type?

I couldn’t say for sure, but I wouldn’t expect it to be that much different from the challenges of making a large instance of any Yajilin-esque puzzle (i.e. having directional clues), when compared to making a small one. Then again, as I suggested above, making one of these at any size is a true pain in the ass, so making a large one would definitely not be a cakewalk.
As for how to make one of these at all, I don’t think I could really tell you. My methods involved a ton of restarting and a substantial time investment.
