Sentimental K is a top-down 3D action roguelike. There is no full plot in it. It will be controlled by a girl with white hair. She is able to run in different directions, dash, perform various melee attacks, shoot, and so on. The combat system is based on timings. Fights require a good reaction from the user. The main feature of the indie project is the random generation of almost everything. Here, with each new run, the locations, the order of appearance of ordinary enemies and bosses, skills, equipment, and so on change. This title has enough content for replayability. This indie game has 5 types of weapons, 13 leaders, 78 skills, 132 artifacts. The abundance of abilities and items makes it possible to experiment in creating a variety of builds.

There is no meta progression as such in the SK game. If the character dies, the user has to start the race again. Also, there is no permanent upgrade of the heroine. In order to progress a little further each time in a video game, the player needs to improve his gaming skills. During fights with bosses, you need to look for vulnerabilities in your opponents and remember their attack patterns. After completing the title on easy mode, a harder difficulty unlocks. Controls are designed for use of a keyboard and mouse. There is also support for gamepads, but it is only partial.
