This game would be more fun if you could send waves out whenever you want (so you can send like 50 waves out, and nuke em twice and get like 100kish)
4/5
Superb game, 1000/5
Also the easiest 50 points I've ever earned. Only took me 2 runs through
Hint: Focus on getting the x50 multiplier first, then go for 2,000,000 points (if you get 2M points, you have 2k+ shapes).
