I haven't finish the demo, yet. However, the art is really great that I really like to support the dev. Unfortunately, your patreon only have $10 option with 3 patreons. I believed if you create more tiers with lowest being $2 or $5 there will be more supporters and I gladly be one of them but I, unfortunately, can't guarantee to be able to support $10 every month but I can manage with $5 or $2. I'm sure many would feel the same and support you more.
