on level 16 on blind mode, i dominated the map almost instantly, gaining both turrets and destroying any ships they had on other planets. i proceeded to capture every planet while keeping them surpressed at their starting planet (they couldn't get past the turrets). i built up my army of 295 ships, captured the warp, and proceeded to destroy their only planet . 295 ships vs 2. it felt good
so even if you don't complete all the objectives, but infect/kill the entire population, you CAN go back and do it until you succeed at all the objectives
after completing the only level to stump me (35) this game was far too easy and a lot of the puzzles were repetitive.
so its not bad, but its also not very good. Reminded me of the impossible quiz from a few years back, but much much simpler. 3/5
