Are you referring to the sum total of two comments asking for a promo at the time you posted this?

Hyperbolic top level comments with phrasing like "the number of people" to make it sound large and extreme and calling it "appalling" when the author is offering promo codes in their post and people are subsequently requesting them is the actual bad behavior here.

The author explicitly said to ask for one if needed, why would it be appalling?

This isn’t a community of people interested in playing casual mobile games. Their interest in playing this game can be assumed to be low. The author is trying to have a discussion about the game and might get more interesting feedback from people who can play the game, and is explicitly offering promo codes because of this. And, $1 is material to many people.

Honestly, there are people that will always want free stuff, and that just needs to be accepted. Free users can give feedback, can spread info by word of mouth, and can also turn into paid users. A smart developer will try to use them as an asset - which seems to be the authors intention by offering promo codes.

I appreciate the sentiment honestly. I am a student and so honestly don't have a ton of money myself, which is why I wanted to give the option to try it for free for those on this thread (for any reason, not just saying if they are a student or low on money). Obviously I really appreciate those who are buying it though :)
