Thank you for playing!
Yes the game is very much unfinished, the entire main room and all the character sprites still being just placeholders. Will be adding a lot more characters to chat to, and fill the room out.
Thanks for noticing the graphics in consideration for the tile limits, I probably spent too much time trying to optimize them! And yes this is GB/GBC with the palette applied globally. It was important for me that it still ran on the original Gameboy, but I wanted it to be black and white from conception.
