  BattleTitan Boss Dev. — June 2026

  BattleTitan Dev. — June 2026Since March, many events have happened, so this development report covers roughly three months. Compared to the carefully planned schedule I made at the beginning of the year, development has taken nearly twice as long as expected. Boss Logic & Combat TestingLogic development and combat testing for Battle Titan bossesSprite work and pin-up artwork for more appealing bossesStory scene artwork production (requiring significant time and development resources) The global game development market is currently very difficult, but development continues.The biggest advantage of solo development is this: as long as the developer still has purpose and determination, even if funding runs low, the team does not collapse and the project does not fall apart.Progress has been slower than expected, but I continue moving forward by finding new ways to keep development going.

Boss Combat DevelopmentArcade Mode follows the design philosophy of classic masterpieces in the genre, while Story Mode is where I challenge myself creatively.The arcade combat structure is heavily inspired by "DoDonPachi" and "Crimzon Clover."The Story Stages maintain the core game play of “shoot and dodge,” but beyond that, they push further into experimental territory with bold creative ideas and unique mechanics.2. Battle Titan Boss Artwork — “Old School” DesignThis project originally began from a simple desire: “I want to draw robots.”That is why the game features old-school mechanical designs inspired by works such as The Five Star Stories, SDF Macross, and Mobile Suit Zeta-Gundam.As a result, this top-down shooter became something filled with both romance and madness for a solo developer.Development has taken many years. To sustain the project ...

  Due to changes in our development environment in 2026, this announcement was delayed while we adapted.A. We withdrew from our previous setup and needed time to adjust to a new workspace and equipment.B. Upgrading hardware became impossible due to the global rise in electronics prices, so we expanded storage instead.C. We reinstalled the OS as a minimal upgrade. Fortunately, since this is not a 3D-based game, no major issues occurred.D. We had planned to participate in the indie game show “BitSummit” in Japan, but this became impossible due to the development schedule.1. Boss Design & Detailed Development (Arcade Type & Fighting Game Boss Type Dev.)We refined the combat design of each boss and improved the structure to better reflect precise design intentions. Debugging is ongoing.Increased bullet pattern density and expanded attack phasesImplemented destructible parts system for bossesDeveloping both arcade-style bullet-hell bosses and fighting game-style bosses2. Scenario Mode Script & Illustration PlanningWe are defining stage intro scripts and event scene concept art.Once production begins, changes will be absolutely impossible, so we are proceeding with extreme caution.Due to the length of martial arts terminology and long English sentences, we are adjusting UI and dialogue window sizes.\\ & the length of the UI & dialogue window is being modified because of the \ in the script.3. Release Schedule PlanWe are planning a launch in December 2026 and have adjusted development and QA schedules to align with the Steam Next Fest in October.First half: Boss battles and event script productionSecond half: Debugging and QA-focused developmentThe date for the “End Game” has been set. Thank you for reading.
