I haven't dug around on how to get CE to work in LD+ seeing as LD+ has a built in cheating system during character creation. I've opted to use that instead. Though I suspect it's just a matter of googling around a bit if you want to use CE instead.

Try if it works with 4 bytes, if it doesn't, switch to all. Honestly when it comes to Cheat Engine I just went through the tutorial once and after that I just about googled and trial-and-error'd my way through using it.

Cheat Engine's own website

Right under the giant green "Download Cheat Engine" button, there is a small blue hyperlink that says "Download Cheat Engine 6.2 for Mac".

Some anti-virus programs say Cheat Engine is a virus just so you know. I personally believe it to be safe and I've used it for a fair amount of time, but if it puts you off then no-one will blame you.

I'm assuming you mean the door in the Abandoned Laboratory still. That door is designed for you to find out that you can change your mood, and that the mood affects your stats. In the same tile as the door, there is a separate interactable to the left, The Jigsaw Puzzle. If you solve that, it will boost your nimble up enough for you to unlock the door without any grinding.

I don't know any way to cheat your stats, however if you google "rvdata2 editor" and press the first link, or just press it here, you can upload the file onto the site, edit the amount of credits you have and redownload it and replace your original file with it. However I found no luck in attempting to use it to edit the stats for my character, though I could've done something wrong.

Edit: Just like Indivi said, you can use Cheat Engine. I didn't think to add that one because I couldn't make it work. But I've found out how to now.

If you intend to use Cheat Engine for Lust Doll, or any RPGMaker game, any value you have needs to be multiplied by 2, and then you add 1, before you search for it. So if x is the amount of credits you have, then you would do x*2+1. (If you have 200 credits, search for the value 401, etc.) And then when you change the value you would have to change it to the value you want, multiplied by 2, and then add 1. So the exact same process as when you search.
