Small Delay On Next Update!

We're pushing hard to complete the forest area of the game. We've completed most of the content now but we wanted to include the final boss battle with the Fire Wizard! The next update includes a lot of new content (including some new heads), fixes, and improvements. So hang tight!

Yours truly,
Seabass & Topher

The Quality of Life Update (Build 0.3.5.0)

Hey everyone! This is our first official update for Duke of Defense and we want to make sure we've left you with a good impression of what's to come. This update includes mostly quality of life changes that we felt were necessary to take care of before pushing forward with new content.

  • New tower upgrade icons
  • Added 4 heads to be unlocked (later in the game)
  • The tutorial will now prompt you to press SELECT when showing the UI at the top of the screen
  • Fixed various grammar issues in the tutorial
  • Cannonball impact replaced with fireball impact
  • Removed the checkmark displayed above platforms
  • Made pausing more polished (just made instances not flash for the first frame)
  • Broken hearts appear above the player when taking damage that affects lives and the castle does the same
  • Tooltips that appear throughout the gameplay to help explain various mechanics
  • New gameplay setting that allows you to turn off automatic menu prompts
  • New platforms that indicate a level completion in 3 tiers

    • Not completed
    • Completed with lives lost
    • Completed with no lives lost



We have started work on the next update already so you can definitely expect to see the complete forest section of the game fairly soon. We have another boss battle, new levels, and more heads right around the corner!

Regarding issues with audio problems


We've seen a few reports of music going silent or not looping correctly. We have yet to verify what the exact issue is or what we can do to prevent it. We're keeping our eyes open and looking to resolve this problem as soon as possible.

Yours truly,
Seabass & Topher

What are we working on?

We've been trying to recover from the pre-release grind we were on and begin the next big steps for Duke of Defense. The next update includes an unhealthy amount of changes!

  • New platforms that indicate a level completion in 3 tiers.

    • None complete
    • Completed with damage taken
    • Completed with no damage taken

  • Made pausing more polished (just made instances not flash for the first frame)
  • Broken hearts appear above the player when taking damage that affects lives and the castle does the same
  • Tooltips that appear throughout the gameplay to help explain various mechanics
  • New gameplay setting that allows you to turn off automatic menu prompts


Of course we've done more than what is listed above but what matters to you is that this update will be made available next week. We have new content in the works as well but we may have to roll it into the following update. We have spent most of this week focusing on polish and listening to your feedback.

Yours truly,
Seabass & Topher
