For the ship battle bug: it works only, if the browser size size is default. If you changed it (either decreased or increased), then the ships won't hit each other. In Firefox, you can change it with "CTRL" + "+/-" or "CTRL" + "mouse wheel".
There is potential in the game but it is hard to play at the moment. 1) The first level should definitely easier, a tutorial level or something. 2) The power should start from the no/max power, not from the last power. 3) The game stopped working correctly after few minutes: the cannon didn't shoot presents (appeared on the top-right corner) and the order of the houses was rendered wrong (far building was in front of a near building).
I just bought the basic flooring, it saw 5k, so very expensive, THEN it said that I have to have 500 guild member to have it for real. I can't roll it back, so I just lost 5k, this is just stupid, I'm out.
Please put a feature to the end screen to play further when the inn is opened and you have your team members. I need the 4th key and it is impossible to defeat the zombi dragon alone.
