This game is not Crysis AFA-graphic-IC , and it lacks something in playability, but I still rate it 4/5 (my exact rate is like 4.25/5). Keep on upgrading it, and it'll have my 5 soon ;) (estimately round Chptr 4-5 ;) )
@ urmelhelble - forget the missile launchers, AFAI see it's easier to use lasers -> pulsers for very first missions, and keep mining @ more than 1000 per minute; don't upgrade miners, just build them a lot. ;)
I don't understand ppl who complain about 2000m. run (card achievement) ; I got it , like, after 3 try. Nerds? Got almost 4k in less than 10 tries, aspiring hard badge as it is at the point where it should be. Good game :)
