0.3.0 - Too many changes to list
There have been a lot of changes. I'm only going to list the biggest changes to gameplay.


  • Removed the illumination mechanic
  • Units are now configurable (targeting zones and target priority)
  • Added unique boss relic drops
  • Added potions

0.2.0 A lot of UI work.
Mostly UI work, but a decent sized patch. Skipped to 0.2.0 because of the gameplay change with removing target priority. After experimenting with this a bit, I think I may bring back target priority but in a "If the prioritized target type is not found, target anything else" kind of way. Overall, the old way would make more sense if I allowed player programmed customization of the units.


  • Several UI improvements
  • Bosses now drop chests that you have to attack to retrieve
  • Gold perk removed, in favor of always receiving that bonus gold for the boss kill
  • Fixed a longstanding bug that would not immediately show it's effects, but would eventually cause a crash
  • Sniper rifle now displays damage and hit effects in the proper location
  • Fixed GoldGenerator not giving the proper amount of gold from levels
  • Reduced deadlyinventor's saw speed by 25%
  • Slight nerf to burst pistol's recoil and range
  • Added gunmod icon
  • Added hag cauldron model
  • Nerf to t2 weapons across the board
  • Fixed jungle style mags not displays stats in tooltip
  • Fixed missle boss missles causing weird issues
  • icbms now spawn slightly closer, so they appear on the map with the enemy wave
  • Fixed bug with card models becoming misaligned
  • Corpse dealer nerf gold per kill 3 > 1
  • corpse dealer buff increase aim speed 2 > 2.5
  • Removed target priorities. All units now target anything but still only within their allocated zones
  • Slight buff to enemy hp scaling
  • Enemies also now gain a bonus armor after every bossfight
  • Nerfed poisebreaker boomerang slow duration 3.5 > 2.15
  • Slight crusader shield bash range increase
  • Curse weaver bound agony trigger rate buffed from 1.55 > .9
  • Nerfed constructor castle heal per wave from 15% to 5%
  • Fixed bug with missle boss not dropping boss chest
  • Fixed bug with perk potentially choosing nobody
  • Lowered requirement for demolitionist synergy from 3 > 2

0.1.5 Balance changes and assets
Still a bit to go.
