About this game

RHEUM [pronounced: room]
A mass of muscle and teeth lay dormant before you. As you inch your way closer, it comes alive. A sphincter crying for help, beckons you to descend. Your only option is down.

Travel through a fleshly vessel, as an eyeball, collecting rheum [eyeball crusties] to grow stronger in your fight against the infection plaguing this.......body. Collect eye crusties, upgrade your pupils, and clear the screen of bullets with your cornea crushing eye blasts!
