It is Ren'PY everyone has cheats. Search for Unren.bat there is a copy on f95 or manually change 00cosole.rpy in renpy common folder. Easier to use Unren utility
[Tool] - [Ren'Py] - UnRen.bat v0.91 - RPA Extractor, RPYC Decompiler, Console/Developer Menu Enabler | F95zone place unren.bat in the same folder as summer_story.exe run it take option 3. When you play the game you can now use Shit-O to access console. Shift-D will access developer mode you can use it to view variables but they may not show up until you have a value in them. So if you have not earned any Kenny affection it will not show up. When using Shift-O the commands work like this "kenny_aff +=1" will give you plus one affection for Kenny. Some other commands: "derek_aff +=1", "derek_dex +=1", "kasie_lust +=1" this basically works for all Ren'Py games. Some devs have put in things to try and stop it but it work in most. Use Variable Viewer to see the variables, and console to change them. To exit console press ESC. I am sure you can find more on f95 but that is the basic how to cheat on Ren'Py. Use at you own risk changing variable will break some games or cause you to miss content. I think this game is fairly safe, you can add a few point if you need them, you can also use Unren to unable roll back. Roll back try a different chose, roll back use console to up a variable and see if a choice unlocks etc... If you learn more about Unren and Ren'Py you can decompress RPA, decomplie rpyc, and read the script as a .rpy file this will let you see what each choice does you can also extract all the images and view them.
You can also break your game and make it unplyable, so make a copy of the whole thing before you do too much. Use UnRen 0.91, the so called new version 0.11 will delete the RPA and screw things up. Also not a fan of DBZ version just use 0.91 it works, it eve extract all images from Summer Story so you can see what you are missing. Sorry for the multiple edits but I tested version 0.11 and it did not work, did not want to give bad advice so changed link to 0.91.
Hopefully, these two scenes will lead to something in future updates.
