Upgrades do not work as described. Memory makes the game lag massively after a few minutes. You need to look through your code and learn what you did wrong so you don't do it with your next program. An uninspired copy of other games on top of all that.
Reviews for "Planet clicker"
Agreed with hotjesselyntea. And there's another major letdown: no way to either save progress, or to keep track of progress ~ that is, if power supply goes down or whatever happens, then there'll be hours lost to the void nothingness of space. Literally.
How can something so simple and empty lag so much? It's unbearable.
You really have to clean your code man.
Just go play Cookie Clicker
Boooooooooooooooooooooooooooring
