Hi meekimeeki,
We are 2 people with a dayjob and family lives who paid $6000 for the demo out of our own pocket, making this passion project out of our free time. The only reason we can keep making games with quality CGs, voice acting, custom music, etc... is because of the support of our fans. We literally cannot offer the full game for free because if we did, we would have no money to pay our artists, voice actors, musicians, etc... and we wouldn't be able to make more games.
If you are in a country with a currency that puts you at disadvantage, we suggest you follow us on Steam, where regional pricing may make this game more affordable to you.
