Nice
This is a great sequel to an already good game. The first few levels inform you of the game's strategy a bit better, which is good for people who didn't play the first one. A lot of the levels in this one were extremely easy and not much of a challenge, but the new purple enemy made up for that to say the least.
One weird quirk in the game is the pause button. When you pause the game, nothing actually happens, but the timer is still going and the enemy is strategizing. You can hear them popping out tentacles, but nothing happens. After a while, you unpause the game and there's enemy tentacles everywhere. So yeah, the pause feature is rendered pretty useless. The game doesn't really NEED a pause feature that badly though, so it's no big deal. Some of the levels could have been better made though, since a lot of them are extremely easy and don't require any strategy at all. And I'm not just talking about the first few, there are some toward the end where you really only have one option and it eventually leads to victory. 4/5, though good game.
