Hey Everyone!

The Heartworm 1.1 Update is here! You can grab it for 15% off right now during the Steam Autumn sale.You can also now purchase the game’s soundtrack - featuring 60 original songs written for the game. As previously mentioned, with this update, there is a new, optional increased difficulty called “Challenge” mode, with a new costume reward upon completion. This will require much stricter management of resources and more careful decision-making in regard to when to fight or flee. (The original, normal difficulty of the game still exists, of course.) There are also a number of other additions and changes, outlined below:
