I like the game. I beat the end boss once, and can't beat him again :( However, it really needs a mute option. 5 stars though because I keep coming back for more!
I give it 4/5 overall. Great concept, and the game is addicting. I keep coming back to play, so that's something.
I think the 30 at a time thing adds to the strategy, but it's not that obvious the first time through.
And no bugs, that's always a plus. :)
Love the game, great concept. The bugs kill it though. Once the game bugs out, there's nothing to do but quit and start over because game doesn't seem to save. 4/5 for concept. 5/5 if the save worked.
