you do realise most people do this for fun right? if you want a professional game, go look for one, or have one made. This, and many others like it, are games made in people's free time, they have better to do than code all day for free just so you can get off.
seriously, you basically get somthing for free, and you complain it's not enough? have you no shame?
Or does attacking people for no reason make you feel like a big boy? Are you one of those who needs to fuck with people on the internet because you can't do anything in real life? because if you are, no shame in it, but it's not a healthy way to deal with your troubles, just saying.
And if you're not, then that's actually worse; it means you're either an ungratefull asshole, or a greedy little shit who can never get enough. i actually hope it's the first, at least it's an easy fix.
Honestly, i am of the opinion you should apologize; not only does the author if this game allow patreon's to post the link here without trouble, he/she's even quite cool with it. you basically only need to be a patreon if you do it to support the author, otherwise -if you don't want to pay, or just don't have the means- you can just get it here.
It's people like you who drive away such generous creators, and leave only the assholes who don't care about you venomous comments because they only want a quick buck.
