Well, for me this is better than portal for a flash game, because it catches the essence of the flash puzzle in general -- not very difficult btw, could use a hundred more levels :P
Best so far: 300... After 4-5 tries... What's wrong with this 'survival mode'?! I have to say I have played not one or two RTSs, but this one has something messed up and I can't really put my finger on it... I also can't understand why games like this get badges for only LOOKING nice(and by nice I mean the slight resemblance with starcraft). Shouldn't have any badges at all, but now that it has I would seriously recommend making the card only for beating arcade mode...
One more thing -- survival mode SUCKS! You can't really expect people to reach high levels when you grant them only 100 ore per round, that's dumb. I can't kill 3 strikers because I have money only for 2 mines(and that's my best bet omg.......
Overall -- moronic, unsatisfying and UNTHINKABLY hard...
there are a few levels where when i jump a close call and get to my cabin, my image after than can't jump the gap even if i dont touch anything... there are a few bugs with the crates too... overall 3.5/5 for the flaws...
