Fungicide is getting better and better. In the past few months, some art assets have gotten a makeover, and new features implemented.
The new weapon upgrade system gives players a reason to keep going, with each of the four weapons gaining great utility with levels gained.
Killing spree has been revamped to be faster and require more activity from the player. You're given two minutes, but gathering collectibles and murdering hordes of monsters greatly increase the timer. You have to work for that time now!
Many other small features, as well as some optimizations have been rolled out.
Feel free to share your opinions, report bugs, and generally discuss in the game's forums!
