Visual novel in a game jam :o After the game i was questioning my existence which is first for a game jam game to make me do that :D
Like others said the game definetly need music and enviroment sounds like birds chriping in woods or people talking at the shopping area etc. Also the contrast between the background and the character is not enough you should work on that.
Other then these i think its a bold desicion to make a visual novel for the game jam. Original take on the theme and interesting ideas well done :D
