It can be hard to make a puzzle at first when you start out, but when you get the hang of it, it's not that hard. It's only hard if you're completely inconsiderate to the puzzle-making process.
Making stuff is hard without illogical fallacies until you start to get better and better with your puzzle-making creativities. But try to make it logical and your puzzles will become better than these. Thanks to Lilred211 for the hint!
This puzzle is solvable to one logical solution; however, it does require 2D logic/temps to do. This is actually a VERY good puzzle for a first time using 2D logic.
Start by picking a square, I recommend a corner square, and one where the row/column is a higher number if you can. Use temporaries to assume this square is filled in, then solve as much of the problem as you can, assuming that square is supposed to be filled in. One of three things will happen. 1. You'll hit a dead end, where you can no longer prove anything. In this case, pick a new square to assume and try again. 2. You'll hit a contradiction. In which case you'll know that square you filled in HAS to be empty, erase temporaries and keep going. 3. You'll solve the puzzle. Congrats!!
The issue with using temporaries, especially a puzzle requiring HEAVY use of temps, is that it blurs the line between deduction and guessing. If a significant portion of a puzzle must be deduced by choosing a square, supposing it filled, and going until a contradiction occurs, have you merely deduced an incorrect outcome? And what if it turned out to be the answer, did you really arrive at a logical conclusion, or did you guess the answer? In my opinion, the better puzzles require very little use of temps.
Speaking of which, this is very illogical.
