The game itself is great! My new favourite! It successfully stole few hours from me ;-) It is probably one of the hardest if not the harder defense games I have ever played. But now let's get professional now and write a review ;-) or rather some remarks:
1. The tutorial and waves information "windows" sometimes are covering the places where you could or at the moment would need to place a building, you simply cannot see where you can place something because of the writings;
2. The same about the name of the sponsor in the top right corner;
3 The boat sometimes is being created in places from which you cannot move it, or even on land;
4. The last but definitely not least, since it is most irritating: I beat the 10th level, and:
a) it is not shown on the highscore board;
b) I did not receive the medal (the Defender one).
A proof that I did it? The number of stars. You cannot get 28 stars without 10th level. Maybe this level was supposed to be unbeatable? ;-) If so - sorry ;-)
