you need a tutorial
you need a tutorial to understand the linkage of the tunnels. Thus, the player will be able to understand why he can't build his solution.
Except for this, the game is not bad. No bug to report.
Reviews for "FIVE/5"
Interresting Puzzle for less than 5 minutes
The music was quiet okay. The game-play was simple, but for 5 minutes sufficently.
Not really breath-taking, but all in all a good a little puzzle during break.
Maybe a next level will be a good idea.
Excellent idea
All in all, enjoyable and makes you think about how to attach rooms and manuever around the map. Unless all the passages line up, you cant move from tile to tile, which seems to be the biggest criticism in all the comments, so maybe that needs explaining in more detail as most people are trying to move from one tunnel to another without the other tunnels above ansd below joining up. Minor critique however. Id like to see more of this style and some better defined goals for future games of this type.

Great game
Some tunnels didn't match even if they were logically matching. Either it was intentional, or it was just coincidence, but it made the game feel like a long-shot when coming to logical solution.
