I like how much your putting into an idle game as it makes it fun IF I want to do something. I do have one problem. The current size is to big even at a high resolution. MOST people use 1024*768 which makes this huge
The game is good but the last level is too different in terms of how hard it is. The curve should be a little steeper so it gets a little harder but the last level should be a little easyier.
The game is good but the balance is a little off. The carriers are pretty much only worth keeping to take a hit. The battleships are good. There is a counter for almost everything. The best unit seems to be the Destroyers and the bombers. I would suggest when a boss comes use the heavy bombers as they hit the little ships hiding in the big ships shadow which will take care of a lot of problems.
This is a very good game but it is very hard. Fighters seem to the only way of stopping your ship from going up in the first few levels. They are worth the investment.
For thoes who cannot beat the last boss it's acutally not hard. Do not shoot the center. There are two parts to the ship. The botton part does nothing while the top part takes damage. You have to hit the side to take it down.
