The game is made with RPG Maker MV as the base engine, but also quite a lot of plugins and custom coding to make it do things beyond the scope of the basic engine!
I know fully well that RPG Maker games have a bit of a negative reputation in some circles... so thanks a lot for giving our game a try in spite of that! It's great to hear that you enjoyed it so much!
New update will be coming soonish, so do follow us here, or our socials, or join the Discord to be up-to-date! And thanks again for the kind words!
