1.1.3 Update New Boss and Playable Character

Hello fellow eye balls! This update contains some cool new goodies :)

Whats new :

  • Brand new boss fight
  • 4 new mini boss fights
  • New playable character that follows suit of the above mentioned boss
  • A new upgrade
  • Updated some art here and there
  • Possible fix for 1440p displays. (This one I'm not sure on. You'll have to let me know)
  • You can now take screenshots with your standard Steam screenshot key.

There's more but I forgot to keep track of the changes because I'm......near sighted ;0

Awaken the four eyes to call forth the wrath of Crown Cornea and free her children!

If you've enjoyed your time with Rheum, consider leaving a recommendation as it nudges Steam to suggest the game to other people :) If you don't want to, please ignore my shameful request and keep shooting eye balls! :D

This update includes leaderboards so you can compete with friends and other cool strangers! You can check the leaderboards in the main menu. There will be a fleshy skin tab that you can click on. Your local highscores wont get added. Sorry :(

If you run into any issues, let me know. Setting up a leaderboard is new to me so there might be some errors.

Also added an option in the option menu to clear the screen of any unnecessary text, like scores from close range kills and grazing bullets.
