It's a sliding puzzle with a twist: you're not trying to get any piece out or anywhere special, you just need to clear space for the plugs to connect.
The ads are a bit obnoxious, but there is a single IAP which unlocks all levels and removes them, a sensible choice. I will likely buy the IAP because the game is quite enjoyable.
Puzzles are very good and logical, and unlike other games it is clear that these levels are hand designed, each with their own personality.
However, this dev also has a game which is a ripoff of A Dark Room, which makes me a teeny bit suspicious if this game is copying some other one that I don't know. Could anyone do a bit of research on this? Much appreciated
