It's too grindy. You have to spend a lot of time if you want to max everything. Game also lacks some kind of plot, there is no mission debrief, items description, nothing. But overall it's enjoyable game. 3,5/5
Getting three stars is easy after buying regeneration. All you had to do is kill ALMOST all opponents and when you have 1 or 2 left, just get out of their range of attacks and wait till you have full health
The five-leaf clover is a lie!
But on serious note, it was fun while it lasted. After you buy all money upgrades, money becomes insignificant. You should be able to convert it into science or something, because unlike money, science points are really needed and their maximum income is only 20,655. For idle genre, this game is rather short; I managed to complete it for about 20 hours.
3/5
Great music, great graphic, good animation, but that's just it. Game is not balanced properly, there are too many useless levels where you barely felt any progress. Moreover, not being able to choose lower stages to farm is a mistake. I hope it will be fixed. BTW speech bubbles are fine addition. It would be even better if these were unique for specific characters - this would add depth for their personalities.
So it's 3,5/5
