Actually Buff up! videos from Youtube do not work "properly". I have to watch 3-4 of them to get 1 buff... I really feel like cheated. Please fix this problem or remove them. Videos from Kongregate work fine but lately I got cheating videos from Youtube only.
Very nice game 4/5. It seems to be a little bug on mission rate, near the clock. It goes directly from "perfect" to "good", "great" is not mentioned. A suggestion: I would place a countdown instead of a clock. In this way is clear that, as example, to obtain "perfect" it is necessary to finish in 3:30. After the countdown reaches zero, the "perfect" becomes "great" and the countdown is set, let say, 2:30 and so on.
Good game 4/5. It would be perfect if you can buy "global" upgrades with the XP gained (more initial money, more base HPs, more gates HPs, more units damage/HPs/rate of fire, etc...).
