Hey. I'm sorry to hear that.
Well it was free only because it was just a beginning. And I was a new dev. I needed more attention. That was the whole point. Make a free chapter 1 as a demo version. Who in their right mind would give their games for free unless it's a demo?)
And I didn't just randomly switch. I've talked about it in my dev updates on Patreon and mentioned it on my discord server. I know that it's something easy to miss, tho. Especially if you don't follow me, so sorry about that. But just saying it wasn't just a random thing when I decided to get greedy or something) I planned doing so from the beginning.
I do plan to include chapter 2 into the free demo version when the next chapter will be released. So it's not like you won't be able to play it for free. It's just it'll take time. Otherwise, you can always get buy it.
In any case, I'm sorry for this misunderstanding or even disappointing you. I try to be open and connected with players and always ready to hear feedback.
