Thank you for the excellent feedback! I'm already scheming obstacles and riddles for my next build, hope you like them! Also I'll fix the page color thing right away, also found out I gave the game frame the wrong dimensions.
I tried your Linux build, but I got an error:
> ./SeaWar_LINUX.x86_64
Set current directory to /home/kcabra/Downloads/SeaWar
Found path: /home/kcabra/Downloads/SeaWar/SeaWar_LINUX.x86_64
no boot config - using default values
(Filename: ./PlatformDependent/LinuxStandalone/main.cpp Line: 479)
I did a Google search and I found this and this link pointing out you might've forgotten the Data folder. After that I tried to run the game inside the Windows build folder to see if it worked out, but with no success.
I'm sorry for the trouble and I'm looking forward to playing you game!
