Honestly I had a lot of fun while playing this game. It was challenging, specially level 6 which was very tough. The feature of units remaining connected even when the intermediate units die and the fact that a unit can connect to another one even while dying give the game a lot of possibilities when designing new levels. Had some trouble to memorize which unit kills the other, but you get used to it eventually. I enjoyed the music too, but after 15 minutes playing, it becomes a bit annoying. In an overall view, as a fan of simple games, I rate it very highly. Congratulations!
