Ahh. This is the same contest that "minicraft" came from.
Pretty good game. Kept me entertained until I finished it, though some levels were annoyingly difficult.
I did level 10 five times, copying the movements in the walk-through. Every single time the enemies would storm out, and just kill one of my men... even though the surround !'s were there. Seriously... does it need pinpoint precision to work?
It was a wonderful game, one of the best I've played, but one thing bothered me... Collapsing a star into a black hole doesn't multiply it's gravity, or extend it's gravitational influence. A black hole merely allows matter to get closer to it, where gravity can have a greater influence, and any matter orbiting far away would feel no difference in pull.
I like to defend as much as possible, build up a huge reserve of money... add mem once or twice... and then when I am confident my structures will not fail me... I send a huge frickin wave at their base on all rows. It just wipes them out. Then I send a buttload of bats afterward and they eat away at the rest of their HP (since the first time a row is hit, the line is overloaded and all malware is destroyed). I don't know how good this will be in the long run, but it's gotten me up to level 10.
Does the money you collect from a level get multiplied to your accuracy? I had 53% accuracy and around 50k from the level, but only came back with about 25k.
@Fallingleaf: In the browser mode, you can destroy a card for strips. Getting 50 of those strips will earn you "1" free extra card from the card redeemer pack.
Gold is too much of a limiting factor... Almost everything is based off of it. I end up having 100s of iron and gems (from playing just one card each), while I'm hoping that the enemy doesn't make it to my portal before I have a decent amount of gold for a counter attack.
