Regarding the character list: I plan to revamp it later. Currently, having players choose a single character to follow right at the start of the game doesn't seem meaningful.
About mods: I'm not entirely sure what kind of modifications you're planning. The current code doesn't officially support mods. However, if you unpack the game files and want to modify the source code directly, I'm completely fine with that – the game is completely unencrypted.
Oh, I found a bug. Please do not click on buttons of other panels while opening the item panel, this will cause the game to pause permanently. I will fix this bug in the next version.
