Some pretty good connect all the boxes into one continuous line puzzles.

A basic puzzle game in which each level has to be completely filled out with a single contiguous line. The game also introduces new mechanics every few levels which add some twists to that basic idea (e.g., fields that have to be passed through in specific directions, or portals that connect non-adjacent fields). For most of the levels I had to take a screenshot of the level which I then scribbled over in an image editing program: first figuring out the pieces of the line that were logically deducible/necessary and then connecting these pieces with some intuition and guesswork. This approach made even the later levels relatively doable (I never had to look up a solution to a level), but I assume that more experienced players don’t need it.

This took me ages of worthless grinding just to say "Heh, it was easy." and then proceed to make this review. It is NOT that easy.

Liked the game. I'm surprised how this one slipped under the radar. Posting a review to shine more light to it.

One of the best single Euros I have spent in a while. "Minimalistic" fits the gameplay and presentation quite nicely, but doesn't mean the riddles are no-brainers. Easy recommendation.
