4/5, would be 5/5 but the last song requiring 15 achievements to play seems excessive. the amount of previous levels needed to replay makes it seem like it's needlessly padding the game out.
Flamethrower is by far the strongest weapon in the game. Just switch to gatling for the big balls you have to push off. The pause after switching weapons is annoying when you want to switch weapons for just one enemy. Lag-a-riffic.
Seems current gold is connected somehow to toughness of quests. I'm spending more of that money, but only on account of dying in my first encounter of quest after quest, and enemy hit points are now using scientific notation instead of 20-30,000 area.
This quest is taking forever... Kill 44 Ghouls in the Battlefield. I'm at 11/44 so far, and have around 1600 pieces of loot. So it's been at least 1600 fights with 11 quest kills so far.
The instructions are a barely readable wall of text. Breaking it into a couple of pages in a larger font would probably help. It also doesn't need to display every time a new game starts. Also, first click is sometimes a mine. This is annoying.
All of a sudden my workers wouldn't do anything anymore. 2nd island, need the one-star bar to proceed, had to play old levels for enough xp to upgrade, can't upgrade.
Giving credit to who you stole it from doesn't mean you didn't steal it. If you didn't make it, or have rights to the game, then you aren't supposed to upload it. Plus, the game was uploaded (again) only 3 months ago...
