Patch 1.05

Wonderful Patch Wednesday



"I sowed these patches with my own hands." - Charlie "Patches" McGee



Hello again dear community! We have another patch today including some key pieces of feedback from our forums and bug inbox.

Some folks are happier basking in the completionism phase at the end of a full campaign run, and others want to move on to NG+ as soon as possible. We have a warning to indicate when you're going to pass the point of no return with your campaign/save progress.

We also made things a little trickier in NG+ where you will go back to losing a map piece if you lose a Hat Heist mission.


  • Add warning (in English only for now) about final mission
  • Add support for ultrawide monitors
  • Lose map piece on failing hat heist in New Game+
  • Fixed bug: Restart feature in New Game+ sometimes overrides the wrong slot


Please feel encouraged to contact us directly with a video clip of your bug, and your player log at: kenny@kennysun.com. Just put "BUG" in the subject bar.

Your logs (Player.log and Player-prev.log) should be in "C:\Users\USERNAME\AppData\LocalLow\Kenny Sun\Hatbox.

That's all for today, thank you for your continued support and the positive reviews which are helping us to reach new players!

Patch 1.04

Tantalizing Tuesday Patch





As promised, we're reviewing feedback, re-reviewing, reviewing the re-reviews, and making changes to help sculpt this Hatbox into something Michelangelo himself could only dream of.

We're trying to strike a balance between overcoming challenges but not being unnecessarily punished for slipping up along the way.

Patch 1.04:


  • No longer lose your unit if you quit the game in the middle of a mission
  • No longer lose a map piece when you fail a hat heist
  • Fixed bug: Tranquilizers stun you forever
  • Potentially fixed bug where you can get stuck floating above a platform unable to jump



Your feedback is paramount and we really really appreciate it so please feel encouraged to keep it coming.

Patch 1.03

Two Patch Monday


"Do it once and do it right. Do it twice and do it better."





We ran into an issue with the latest patch causing problems for users who were initiating a new save from the demo. While we were at it, we compiled our latest fixes.

Patch 1.03 Notes:


  • Fixed bug: If you use a camera while you have the Technophobe quirk, the HUD gets re-enabled
  • Fixed bug: The tutorial for equipping 2 hats can block input if you select a mission where equipment is not allowed
  • Fixed bug: Frogs can eat enemies that you're in the middle of capturing
  • Fixed bug: You can get damaged when exiting level and an enemy with a spiky hat walks past the doorway
  • Fixed bug: Main menu breaks after you start up the game for the first time and played the demo previously


Keep sharing your feedback, and if you haven't done so yet, please consider leaving a nice review so Steam will be kind to our indie effort and visibility!

Patch 1.02

Happy Patch Monday!





Thank you to everyone who has been helping us by reporting issues and sending us details of how they came about. We're working hard on patches so you can expect them to be pretty consistent, and small in size as to have a low impact on downloading/updating. You might not even notice them patch on, we're stealthy like that!

We LOVE that you are enjoying our game and we want to help craft your player experience into something that feels just right. So we're taking all of the feedback that you provided over the weekend, preparing some exceedingly large cups of coffee and figuring out where we can make improvements.

For now, here's this morning patch notes:


  • Increase number of starter units to 5
  • Give 4 of those starter units a non-negative quirk
  • Give one starter unit only 2 negative quirks
  • Fixed Bug: Tutorial occasionally doesn't detect that you have a Showroom and prevents you from moving forward
  • Fixed Bug: If you have the Quick Draw quirk, the toy bow will use the normal bow's animation when drawing it



Please feel encouraged to contact us directly with a video clip of your bug and player log at: kenny@kennysun.com. Just put "BUG" in the subject bar.

Your logs (Player.log and Player-prev.log) should be in "C:\Users\USERNAME\AppData\LocalLow\Kenny Sun\Hatbox.

That's all for today but you can expect us to be staying very much on top of improving with consistency.

Thank you again for supporting us early, and for leaving positive reviews which are so so important for us at this early stage!
