Hi! Thanks, I'm glad you liked it :)
About developing it further: well, I did what I had planned for this game and told the story I wanted to tell. I don't feel like adding more content with no other motivation than making the game longer. I prefer to focus on improving the existing.
But who knows, maybe one day I'll keep developing this universe, create a sequel, or expand the game. I won't stop making games for sure. But in the short term I need a break ^^
