First of all, without the bugs, I would have given 5 stars! I think the creators of this game are very intelligent! The puzzles are very well crafted. However Is it really bad that many time when we click the undo button, we lose the blocks or anything. Many bugs related to the undo feature. So any time you do a mistake, you cannot really use the undo feature, then, you need to restart completely the level. I cannot believe a wonderful game like that still contains such evident bugs. The bug are easy the reproduce. I am a programmer and can tell that when a bug is easy to reproduce, it is easy to fix. So why it is not fixed ? As I said at the beginning, those people are really intelligent !!! So, why intelligent peoples don't fix easy bugs ?
