The first patch (14th) addresses various feedback and smaller issues:

• Added quit to main menu button
• Added Volume sliders
• Added Graphic settings saving
• Added 4th Page in Settings with unlockable cheats
• Improved Tutorial
• Improved certain environment hitboxes and sounds
• Escape menu now fully pauses
• Fixed shield damage bug
• Fixed Boss 1 exploit
• Improved Beta splash screen
• Added cursor color change on low props

Known Issues: 

• Fullscreen / Window mode inconsistencies 
• Face melter item causes too many explosions with shotguns
• Music Volume not fully working (Master Volume works)
• Recycling certain items causes a crash (Try avoid recycling any items that shoot something)

What we want to adress in the next patch is the more gameplay related feedback, that will come in a couple days.

Have fun!
