I've been playing this game for a while, but there's one thing I don't understand: What do the stars do? What are they used for? What are they there for? The game doesn't provide any explanation for the stars, so we are basically left in the dark about them.
By the way, I've noticed that you've made plans on a sequel. As an avid idle gamer, here's my advice: DON'T. Idle games are games that require maintenance, and many idlers (including Clicker Heroes, Cookie Clicker, Anti-Idle: The Game, and Trimps) stayed strong because their devs updated them from time to time. For this game, updating the game involves checking the overpriced parasite upgrades (this game has a price increase of 9% per level for each parasite as opposed to Clicker Heroes' 6% per level for each hero) and the overall-slow progression (a smoother game would be based on the 5th screen's final cell, which has 20 trillion HP as opposed to the semifinal cell's 80 trillion HP). Other than that, the game's rather decent. 7/10
