No, I said that demo the size of ~70% of the game is quite enough to make up your mind about if you like it enough to support. You know, as solo indie dev, I actually use this financial support to actually make content for my games.
If you are asking about the price of a full game, it's 20 USD on Steam and later on Itch.io. Patreon is 15 USD, but that's a subscription with extras like gallery unlock code, hi res art, etc.
