Valid points indeed. (It really does feel a bit far out there even for a small dev. The public has their rights in comparison to how other devs do their content. For example, varying tiers starting from $1 a month in order to garner more of a following. Starting the inflation rate at the price of a large chicken sandwich combo in my country is definitely a turn-off. I want the dev to succeed but at the same time, I can admit the patreon and content should've been handled more accommodatingly to avoid the amount of outrage happening currently.Let's not pretend you're asking for 3-5$ You're asking people to pay for the equivalent of full-priced Indie games each month while aggressively advertising your Patreon through inaccessible buttons or actions that have no right being in the Demo version of this game in the first place.
If you do all of that, it's going to rub the people the wrong way. Now if you stop mentioning your Patreon every single second you can get, and instead mention it once or just have a link to your Patreon in your main menu- with the combination of a fair price model. I doubt you'll be getting this much disappointment.
Start the game: "Hello thank you for playing Kiss My Face, this demo version is under development. If you would like to help support Kiss My Face, visit us over at [Patreon Link]. I hope you enjoy the experience."
