Denver

Normal Fillomino rules : Break the grid entirely into ominos. Each cell contains the size of its omino, and two ominos of the same size may not touch orthogonally (but may touch diagonally).
Normal Country Road rules : Draw a loop that moves orthogonally through the centers of some cells. The loop must visit each omino exactly once, but may visit any number of cells within that omino from one up to the full size of the omino. If two orthogonally adjacent cells are both unvisited by the loop, there cannot be a border between them.
Arrows : Arrows always point directly at a border between ominos. The number pointed to by an arrow is a valid country road clue for the omino that contains the arrow. That is, the number in the target cell gives the number of cells within the omino that contains it that are visited by the loop. Not all arrows are necessarily given.

This puzzle produced some interesting logic. I don't generally find loop puzzles very intuitive and this was the first country road puzzle I'd ever done.

That was lovely! Outside my usual realm as a solver, but I never felt completely lost along the country road.

Christounet, I am guessing because the song "Take Me Home, Country Roads" was by John Denver.

So fun ! Thanks ! Of course, I had to constantly remind myself of the "orthogonally adjacent cells not visited by the loop" rule quite often to unlock things at various points in the solve.
I don’t get why the puzzle is called Denver though ?

This joins the list of puzzles that almost defeated me until I decided to read the rules XD Super smooth and really fun throughout, thanks zeta!

This was excellent! It took me a little while to figure out how to get started, but once I got going everything flowed super smooth right to the finish.
