Hi Izura! No need to apologize for expressing your opinion. :) We're really happy that you've at least tried our demo! Thank you!
As for purchasing the game, we might hold contests/giveaways in the future wherein you can win a copy of the full game. No promises yet when that'll happen, but you can follow us on our social media accounts (Facebook, Twitter, Tumblr) to get the latest updates. :D
Thanks again dropping by!
