I think changing the image to something more sober and minimalist might be a good idea. As much as I like the artwork by itself, the leaderboard itself is going to cover up most of the image. I don't have any ideas yet as to what a minimalist design that would accurately reflect the spirit of the game would be yet, so I'll keep thinking about that.
I know this thread is a year old, but I played the game on emu before buying it on eBay. Idk if anyone else had this experience, but I was unable to skip the cutscene at the very beginning of the game and the cutscene that plays right after beating Dark Sea of Tears (on emu). Being unable to skip those cutscenes wastes multiple minutes, but I don't know how much faster the loading times are on emu.
Also side note, but Momett's clothes flash all kinds of different colors. It doesn't affect gameplay, but it's pretty funny.
