Good game but has issues
I’m still confused on how to get a full 3 stars on levels though. Even though there are a number of built-in tutorials (with a lot of redundant info), the star system isn’t explained at all. One other review said you had to use boosters to get enough people infected to get 3 stars? If that’s true, the stars don’t really imply skill at passing a level. They just show that you use a booster. I dislike when games do that. I try to pass games without using boosters or gems or whatnot. And if the ONLY way to achieve a full perfect score on a level is by using a booster, that level design is flawed in my opinion.
For that issue and the lacking instructions, I give 3/5. Could easily be 5/5 though because it’s fun. Just has it’s issues.
