Generic Zombie Shooter - Redux v1.3

Its been too long since the last update, so this update will not have as much content, but the features added are a big change. Now that I can begin developing regularly again, the next update will be a much bigger content improvement.

• Talent Trees
  • The old skill training screen has been removed and replaced with a brand new talent tree feature. There are 3 talent trees to spend your talent points on.
    • Munitions - Generally, talents that improve your weapons and damage.
    • Fortification - Improves your defense and attributes.
    • Tactics - Improves your speed, melee abilities, critical ability, and various other attributes.
  • The default key to access the talents screen is still 'T', but can  be changed in the Settings.
  • When you have talent points to spend, open the talents screen and they are displayed for you. Click an unlocked talent (locked talents are darkened) to spend a talent point. If you leave the screen, your changes are discarded. Click the "Accept" button to lock in your changes. Right-click a talent to un-spend a point you have spent.
  • Hover over a talent to see a short description of what it does.
  • Talents have a level restriction (not currently displayed). Each tier of talents unlocks at 5-level increments.
• Achievements
  • The player can now earn achievements for certain actions. Check the Achievements menu from the main menu or from the in-game pause menu.
  • The achievement system is still in its infancy, so there could be bugs I don't know about yet.
  • Achievement progress is saved to the data folder. Do not modify this file or you could risk it becoming unreadable by the game.
• New Escape Menu - Pressing ESC while playing now brings up a menu that allows you to access the game settings or achievements while playing instead of having to return to the main menu first.
• Added the 'Slow Down' status effect which is used by the 'Stasis' talent. The icon for this effect is a red down arrow. The speed up icon has been changed to a green up arrow to avoid confusion.
• You can  now exit the shop and talents screens by pressing the Esc button as well as the button assigned to open those screens.
• Corrected a bug where the soundtrack would restart when returning to the main menu from the settings.
• Various bug fixes and improvements.
