Interesting, but it got tedious and boring by level 17. Difficulty was good, but instructions on cutting could have been better. Cutting is a powerful tool to quickly send power to an enemy or struggling node, that was not well explained.
Good game. Upgrade speed and cannon to max, then bullet strength, finally health and defense. Fun, but short. Worth the play though, took about 20 minutes.
