The game is a side-scrolling shooting-style action game created with "Pixel Game Maker MV". As a special bonus for purchasing the game, we have included the project files for the demo version of "Pixel Game Maker Series STEOS -Sorrow song of Bounty hunter-" in the "STEOS Pixel Game Maker material" folder, which can be used in "Pixel Game Maker MV". The project data, image data, and sound data included in the package can be used as materials for indie game production. I hope it will be helpful to you when you create a game with "Pixel Game Maker MV". Please read the readme text when you use it. In addition, the following bugs have been fixed Corrected a bug that caused saved data to be initialized by pressing a specific button at a limited time when a specific controller was connected.
