This is a good game that is relaxing to play and satisfying when you make large sections collapse.
However, I can not recommend it because the devs seem to be sabotaging the game with each and every update! I can honestly say the game has more bugs now than when I first played it. The very first update I got after I bought the game introduced game breaking bugs and it's gone downhill since. Only one update in my time playing actually improved the game but even that one introduced more bugs that did not exist prior!
The latest update has introduced yet another new major bug where you can now just pick up wall panels from one side of a double sided wall without having to release them first! Missing rivets on one ship I was taking apart that were not missing before the update now preventing me from calling the crane on many items below!
Again, I enjoy playing this game but the newly introduced bugs every update are ruining the experience.
EDIT In response to developer's response: You only address the latest update but that still does not explain the pattern of behaviour I have noticed in the time I have owned the game. All updates have introduced bugs that were not there prior. I have played the game for over 275 hours, plenty enough to know it well and experience many updates and thus make an informed review. This is not just a knee-jerk reaction to the latest update.
OK. So, for the latest update at time of writing I have to abandon a ship I had started before the update, we were not told this. Though it's not a big deal for me as I have plenty of money in game but it could be for others with low money who may not be able to afford to replace the ship currently in progress.
