This puzzle game just goes on and on, adding in new mechanics every couple of levels, steadily increasing difficulty (for the most part). I think I'm in love.
Yeah me and the lads call him the ninja construction worker. He comes in when you don't look and builds a wall just before you turn around. You get used to it. Oh and try not to bump into any walls.
You need to add in a feature that shows when you have upgrade available in other boards when zoomed in on one. Maybe a small red dot that moves around the sides of the screen to point to the board that has the upgrade.
This is the most amazing HUD I have ever seen in any game hands down. I enjoy the fact that it shows where to shoot to hit a moving target, something that in most space shooters is learned through practice while here you can just jump right in and start blasting.
@luis1126: There is no beating it, the hellstone goes on forever, generating higher levels of itself until the code gets an error when it gets too high level.
Some simple math to figure out which ore you should be working on to get the most money: First divide the health of the ore by your total damager per click (if the result is less than one, round up to one), then divide the money you get by that. The number you get will be how much money each click is worth by mining that ore.
There are two things I think could improve this, both of which are cheats. A lazer gun cheat where you can shoot the zombies with lazers, and zombies keep momentum with dragging.
I've counted it and I hate to say it but there is no way for the cat to survive without the ration behind the airlock. If you could either get past the airlock or fix the other food machine you would be fine with the cat but I do not see how.
