One, the game is still in development, so the progression of stats isn't finished. There'll likely be more / somewhat faster ways to increase stats in the future.
Two, there's little point to getting that high of stats (and it may be hard capped for now, it was at 20ish the last version I played, 1 or 2 back), since there's no point in allowing you to spend ridiculous time grinding a high stat if there's currently no scenes for it.
Three, cheat engine would depend a lot on how the game is coded, namely what type of variable it actually uses to track stats. A far easier way to cheat is to simply edit the save files, which are in a text format. There should be a convenient shortcut included in your game folder for the save file location, but it'll be something like C:\Users\[user name]\AppData\LocalLow\One-Handed Games\Pizza Hot\Saves if you don't have the link for some reason. Use notepad++ (or whatever text editor you prefer, notepad++ just helps when looking at code) to open the file (right click and select "open with notepad++". Use a search (ctrl F by default in most things) to find exhibitionism, and change the value of it to what you want. Though like always, backups are recommended in case you break something messing with the save.
