Recently I've seen a lot of free skill matching games, and I realized that it seems like something I could do, so I'll give it a try.
Because this game has quite a lot of moves, I can organize the logic of these moves clearly, and then each of them can be seen as a separate skill, represented by a skill icon, so that the player can use these icons to freely combine skills, and the game should become more fun after that.
During this time I will often post the progress of my development of this free skill matching system.
