A downloadable game for Windows

What ?

1D Puzzle On The Line, or 1D POTL is a puzzle game in one dimension. Yes..., one dimension. It's very different from our world. It means you can only move left or right. Nothing, even the graphics, go up or down. You are stuck on the x axis.

What ?!

Calm down. The goal of the is to move to the exit. Easy ? Yes, but, the exit is usually closed and you must paint the cells so it matches the color of the exit and then it'll open. Moving affects cells you cross depending of the cell color you were.

How ?

  • Move the mouse left or right to plan your movement
  • Click to validate the movement
  • Press R to restart a level
  • Press I to hide the interface
  • Hold Escape to initiate the doom sequence that will exit the game

Why ?

This game has been made in less than 48 hours for the Game Maker's ToolKit Game Jam.

You can play the jam version, or an updated version that fix things that were in the original version.

Enjoy !

The post-jam version does some great improvements! I actually understood this time, and I had no more issues with colors! Well done.

Hey, thanks a lot ! I'm glad my improvements are worth it !

I really love the use of screenshake as you exit out

Hey, i think it's because of the name but i can't open it because it's "potentially dangerous"

It's probably because my game isn't on Microsoft white list. So, to be sure and because only a few people have downloaded the game, Microsoft is "protecting" your computer by preventing the game to launch.

You can still launch the game by clicking "More Info" then check the "I understand the risk and want to run this app" and finally click "Run Anymay" button.

Sorry for the inconvenience (^_^;)

ohhh i just had to extract it XD Maybe you should include that for dummies like me.

Oh, okay. I added a line about the extraction.
