Open the console with SHIFT-O

To cheat money (or "gold" as RPGM calls it):

game_state.party.gain_gold(10000)


To see game variables:

game_state.variables.print_values()


To set game variables:

game_state.variables.set_value([variable_id], [variable_name])


for example, this sets the aunt, sister, and mom's relation in Incest Story 2 to 100

game_state.variables.set_value(1, 100)
game_state.variables.set_value(3, 100)
game_state.variables.set_value(5, 100)


with the disclaimer that games might behave weirdly if you go setting variables to crazy numbers.
