achievements...please.. everything else is just perfect to fill my "factory balls" little emptyness (after beating and replaying everyone XD) i will try the app today :D
the last part.. after beating the final drillboss.. (and before you get the key) ARGH! my nerves just went out of town... we love your saga..(me and my ingame stress) :D
This is the exact example of my definition of "Games that are pure artistic work" (and sadly, there's not lots of games who can have this title, at least for my opinion) excellent work, keep it up! cheers from Argentina, my friend! :)
