Cute minimalist puzzle game. Some levels are very easy, some are quite tricky. If you get stuck, you can see the solutions on the letter page. The game is well-designed and relaxing, and I thoroughly enjoyed it.

Minimalist puzzle game, with a nice aesthetic presentation and beautiful soundtrack which make it quite relaxing. It's not very difficult, but with enough mechanics to not make it boring.
And yes, you can find the solution to the puzzles if you check the hearts in the letter. But where's the fun in that?

Sequel to One Line - draw a path through the grid, following various rules. As a puzzle sequel, it's passable - I didn't think the puzzles were as tricky as the first game and there are only 40 levels instead of 50. But for 89p, I can't say I was ripped off.

The extra gimmick of this one - decode a letter you've been sent - was an annoying waste of time though. After you've solved ten levels, click on the missing words in the letter and get shown a pattern, which you then match to the solutions of the grids you've just done. Since some of the grids have multiple solutions, the patterns shown may not match what you found, but it's just click the one that looks the same. The patterns don't have any meaning, it's just 'Here's a shape, find the one that looks the same.' It's not a code, it's putting the shape in the hole like you did when you were in kindergarten.

And the reveal at the end was obvious from the start. The whole thing just got in the way of the game for no good reason. Also, the way it works means that you can see the solutions before you play the levels.

As I say, for the price, it's fine. I would just honestly have enjoyed it more if they had just stuck to the basic puzzle and not bothered with the extra bit.

This one is maybe worth buying on sale. There's very little content (beating the whole game took me barely an hour). This game is better than its predecessor "One Line" by the same devs; it feels more polished and was less frustrating to play.

Great value for a $1 puzzle game. Levels were a bit easier than the first one, and there were 10 less of them, but it was nice to have a theme. Took me about an hour overall. An undo-to-clicked-square button would be nice since I don't always want to fully reset the puzzle if I get one turn wrong.

Quick game well worth the $1 price. Time to complete is going to vary widely based on your puzzle skills, but there aren't any hidden tricks or traps to make the puzzles harder than intended.

It's really cheap, and pretty fun. Though at times you'll get an awfully difficult level in-between really easy ones.

Simple and relaxing. The fact of being able to move backwards allows the game to be challenging without being frustrating, simple but well-crafted concept.

Nice sequence. Collecting the puzzles to solve the letter is the charm of this version!

Fun, relaxing and a game with great concept! The letter that unlock pieces with codes that you get passing the levels is a big plus!

one line: letters and codes is the largely similar follow-up to one line, so my review won't be much too different either. the game still wants you to draw exactly one line on 40 levels to remove every tile, plus there are a few new mechanics on top of ones already seen. walls limit movement options, double arrows make you go in that direction until you hit a wall, other arrows place blocks on both sides of their square.

the main new thing is the 'decoding' aspect, which simply means going to the letter screen and matching solved levels to hearts hiding parts of the text (it's a love letter, you see). I appreciate the game not interrupting the flow by bringing this up after every level, I also understand making things interactive means more player engagement and can be fun, but there's not much to it in this case. levels unlock in batches of 10 after all the available pieces are placed, so best to do the revealing in batches as well.

mouse and keyboard both work, arrows/wasd for the latter and don't even have to hold the mouse button, just click the yellow square and move the mouse around. you can go back on your selection easily if you want to change something, no need to restart (there's a button and 'r' on the keyboard).

with a lot of ground already covered, it can be finicky to get back to an earlier junction, and while levels appear line by line when you first load them, reset is instantaneous, waiting doesn't get in the way of puzzling. especially with right click functionality letting you click the line anywhere to delete what comes after. you can click the current tile first to stop the line from moving if you want.

nice minimalist presentation with calming piano music and all the necessary settings: separate volume sliders, windowed mode with a resizable window, level select screen and an exit button. besides the level select screen you can also go back and forth between completed levels by clicking the arrows on the sides.

not much else to say, if you like this sort of thing, give it a go, it's very much worth a dollar. I found it trickier than the first game, still not too tough, should be doable in less than 2 hours.

I was looking for a game what I like to call, 'my after work degas' and this fit the bill perfectly. The game mechanics worked fabulously and each level present a good challenge. I'd highly recommend this if you're into those old pencil type puzzles that required you to make a shape without tracing the same line twice.

In short, the devs put together a really great game! Go ahead, give a try! You'll see what I mean.

you can see the solution to the puzzles in the letter when you mouse over the hearts. Bad puzzle game and I suspect that the positive reviews are alt accounts from the devs. If you are reading this make an actually good game instead of shovelware for once and maybe you could make rent easier.

for the second half, I couldn't stop myself from cheating. :(
the new mechanics in this one line game are really good and I think there were enough levels to not overstay they welcome.
