While I wouldn't say that I live in a poor country at all, I will say this:
1. I'm working on this by myself and can only do so much every month.
2. Unlike many games in this category, this is not a VN. There's a LOT of coding, UI design, gameplay mechanics/balancing and bugfixing, that you don't have with a VN (at least nowhere near this extent).
3. This game is under development. If you want to play a finished game, just wait for it to be finished.
I would love to be able to add more content and make bigger updates, but right now it's just not possible.
However, I do think that in 2-3 updates (when all girls and levels are implemented) it will speed up considerably.
