[list] [*] Changed the save system for better performance and later updates. Old save file will not work anymore but new one should be compatible with newer versions of the game. [*] Increased the difficulty. [*] Added a retirement system and a shop in the main menu. Players can now retire with their current class / main char to get credits based on their performance. Credits can be spend to buy perma upgrades (currently just 3, more will be added later). [*] Added a short tutorial which explains the basics. [*] Reworked the UI a bit, now you can close windows by pressing the right mouse button instead of X. [*] Fixed some bugs. [/list]
