Step Up Patreon/Need To Add Higher Tiers.

Thinking of adding new tier for my Patreon. I really need to step up my game. Need to make higher $$$ tiers and offer something to be worth it. Maybe doing comics again . I'm just too nice to raise my prices/tiers, so i hesitate a lot. XwX;;;

Any recommendation for a $7-15 tier? What should i offer? Need suggestions~

Would adding a higher tier to play my Game Demo be ok?
