All from "Silver" tier, plus:

• Full versions of the game for VR and PC - three girls, can pose, can undress
• Access to the latest experimental builds of the game showcasing features still in development (like animation system or morphing system to customize a girl). These builds will be unlocked immediately after release of Mirage 0.3
• Special Discord role: Gold

By choosing this tier you speed up Mirage development significantly. I could spent less time working on my office job and put more time in Mirage instead.
