Hey, we were extremely delighted to see that you like the game so far and made a video about it! Your guess in the video was correct: The engine we are using is RPG Maker MV. You already linked the game's itch.io page so that's all we could possibly ask for :) We also have a Steam page for the people that would like to wishlist the full game (4 chapters) there. Please remember that there's a guidebook for the game, you can find it inside the game's folder! The guidebook is helpful in case you struggle with a quest or puzzle. Really excited to see you play the rest of the game :)
