The game is very good and quite unique; the concept and overall idea really stand out and feel different from many other games. However, unfortunately, it suffers from optimization issues, especially considering that it uses a PSX / PS1-style low-poly graphical approach. Performance on low-end hardware is not what one would expect for this type of visuals.
Despite that, the game is still enjoyable and clearly has a lot of potential. Another important aspect that would be great to improve is the save system. Having an automatic or more frequent saving system would help prevent progress loss in case the game crashes, closes unexpectedly, or encounters an error.
For additional context, I am playing on a low-end system with an Intel Celeron 4500N and Intel® UHD Graphics 800 integrated graphics, so these observations are based on real performance limitations rather than high-end hardware.
Overall, with better optimization and a more reliable saving system, the game could provide a much more solid and accessible experience for a wider range of players.
