Over a month without a patch not the schedule I am aiming for but somewhat justified due to health issues. Also I've done a lot of work for the mobile versions, which are coming along nicely. But here's a long overdue patch for you with some balancing and bugfixes!

Added

• The game now tracks your win streaks
• New achievement Relentless: "Win 10 runs in a row."
• New achievement Unstoppable: "Win 5 runs in a row on Overload 10 or higher."
• New achievement Double Trouble: "Win 2 runs in a row on the highest difficulty."
• Core Defense now asks for your permission to send anonymous usage data for balancing and improvement purposes
• Repeater details now show the attack speed increase and overall limit for the kill bonus

Changed

• All difficulty levels have been reworked: all reductions for roll chances and reward amounts have been removed in favor of more difficult mobs
• You can now always start the wave without building all walls: now only towers have to be built to start the wave
• The description for the Singularity achievement now clarifies that abilities are not allowed
• Giant Kite damage 5 4
• Colossal Kite damage 16 12

Fixed

• The music is now properly looping (big thanks to Failix!)
• The ESC key now closes overlays without opening the menu
• Fixed softlock sometimes occuring when deleting profiles
• Removed obsolete tip regarding cooldown reset
• The endless button no longer appears when you die on wave 51
• Towers uncovering the fog of war now take range modifiers into account
• Abilities now play sound effect when used
• In windowed mode on Mac there now is a title bar to drag the window
• Fixed startup issue on Mac
• When loading a game saved while looking at the map during reward selection, the button now properly says "Claim reward" instead of "Start wave"
