Edit: the original images were missing a 2 clue in the bottom right cell of the "door" - fixed now.

I got a little carried away. One puzzle a day? More like one puzzle a week. And I still don't know if I like making puzzles, particularly. So I might not do more.

But it was an interesting experiment: I ended up drawing a picture with the grid, but not with the loop that forms the solution.

Other than some of the stupidly tiny line segments, I'm pretty happy with how this turned out. I managed to include a bunch of the kinds of deductions that I like. So... hrm. Hope it's not too hard, especially if people have only done square grids before... feel free to ping me for help?

Also with the cells having a variety of numbers of sides, I'm experimenting with two-number clues: filled in minus empty.

@JoshGrams You have two solutions here, I'm afraid. There's a second way to resolve the bottom-right corner of the door, as seen here. The puzzle is otherwise impressive, and rather brutal (I was so stuck on the upper-right that I was wondering if it had multiple options as well, but sure enough, there's only the one that works).

@Zotmeister Dangit. I meant to have a 2 in that bottom-right cell but I must have hit Undo one too many times when I was switching clues around. Thanks!

Ha, that top right corner is fun. I love deductions with pairs of -1 cells where one choice would form an island, but they go through another cell to do it. And 2-pentagons or 3-pentagons are maybe my favorite shape: so many possibilities until you rule a side or two in or out, but then they can chain in fascinating ways.
