The internet is an infestation of trolls, critics, and a bunch of children who don't know what they are talking about.
Some are legit kind and actually have the common sense to actually say something good.
Instead, those pricks are being negative jerks while saying: [yer game iz bad] without even knowing the effort and time it took to make one.
I look at other dev's work and I still see whiny asshats commenters who whine at the slightest inconvenience.
Even games that are ACTUALLY GOOD gets these toxic comments so I don't know what the fuck is their problem.
Don't listen to them, listen to people who actually care about the shit you do.
I'll be personally honest, pirates will always be around but from a marketing standpoint.
It's just a free advertisement, people who liked your games would definitely search for the dev and throw cash in it if they feel like it.
