We are really sorry that we didn't manage to implement a tutorial in our game, because to merely complete the existing content had cost all our time😭 to write an instruction in itch.io page is the worst but also the last and only choice to make. Next time we will learn from the lesson and manage our time and resources more reasonably, attach more importance to help players understand the mechanics in an easy and instinctive way.
After voting ends, we will update our game with a tutorial, and also fix some bugs. Thanks for your advice. Hope you had enjoyed it!😊
