Patch Update 33.4

Howdy Folks!

A huge thanks for all the feedback and support. Great to see all of the new and existing players enjoying Mercury Fallen. Over the last couple of weeks I’ve been working on tweaking and fixing a whole bunch of things. There are still more tweaks and fixes in development, but I wanted to get a bunch of them out the door now.

There are more tweaks and fixes coming, but keep an eye out for the next Developer Log where I’ll cover some of the larger changes and additions in development. Thanks everyone and have fun out there!

Check out the release notes below.
