In relation to the pirated 93% - you should impliment a itch.io/patreon/subscribestar etc login.
Offer up to 0.4 for free as a demo, then unlock the rest by logging in.
The login will check if either game is owned, or player is currently subscribed on Pat/Sub etc.
That way you offer the whole game, a demo, and protect yourself and your income stream.
A couple of other games do the same for premium content (outfits or cheats etc) but you can literally do it to unlock the full game after demo.
