To do list:
* High Score (local offline and online)
* Simplify the uppgrades for new players (maybe dont show all 10 skilltrees from the start?)
* Explain the game somewhere. Readme file? (Users who want to know everything)
* Lower the sound by default (even more)
* Esc should pause the game and open a menu. (Use the half pause mode).
* Save file (its half done, need to build the anti cheat).
* The player should get a gun from start or early game
* The green ball (Follow me) is hard to grasp. Make it easier to understand whats happening (Visuals? Lower the cooldown?
* Its hard to play when the half pause is active. Try slowing down SpaceWipe instead of being stuck, maybe also add visual counter?
