console commands dont break the game, you can even use mods as walkthrough guide and it won't fuck up your saves. It only breaks when you use a function made by the mod that isn't part of the game, as stuff you have to choose between 1 or other LI and you use the mod to have both. I replayed the whole game because I lost my saves since I got a new pc, and season 1&2 had a mod, season 3 (the newly updated with ep 10 included) I played with no mods and I had no problems with my saves.
If you wanna use console, you have to go on the BAD folder/renpy/common. then look for a file called 00console.rpy, open it as notepad and do search Ctrl+F and search for "Config.console" then when you find Config.Console=False, you change it to "True", save and exit. Then in the game you press shift+O to use console.
some commands:
money=(number) can be 1to5 till ep.7 or 1-10 afterwards.
mansion_money=(number you want)
pp_money=(I usually put it around 20-22) is good enough. This is for party planning.
dik=(1-20) to go from dik/huge dik/massive dik. (changing dik score)
dtype=(number) to change dik stats - between dik,neutral and chick. It isn't that important till ep8. Since by changing score you usually change the stats. After that I found out that you need not only to change the score, but also the status.
affinity=( either "u'DIK' or u'NEUTRAL' or u'CHICK'") to change between those affinities.
On previous brawler you can increase stats by:
sports_mov=4 (to max moviment)
sports_pow=4 (power)
sports_dex=4 (dexterity)
sports_hp=4 (hp)
you can also add roundbound kick, healing and counter. i forgot the commands though because I never needed to use those, I didn't check console to anything on season 10, but those are helpful to build up your mc.
