@trakorof Ah, so sorry I didn't see this earlier!! Might have been because I left the window open for hours, typing up my Draft bit by bit and the forums didn't send me an e-mail about your post either. It seems that I would get a notification e-mail only for the first person who posted after me, but I am not sure. Anyway, thank you so much for taking time to share your thoughts!
I would like to know more about the checking of X and Y coordinates and how specifically it can be done. Could you please elaborate on this?
Yes, RPG Maker has an Command to check X/Y coordinates of the player or an event
To do that you need to create 3 new variables, one for X coordinate and one for the Y coordinate. If you need to check the coordinates of the player, "PlayerX and PlayerY" would do. The Other one is a variable just for info later, you will not directly use it.
Now to check their coordinates, create an event (No graphic, parallel process) that does this:
Control variable is simple, just use the variable created (PlayerX/Y) and check Player X/Y position respectively, you could also check and event X/Y instead, on the same box;
"Get location Info" is an command available on the third page of the Event commands, dont know if youre using VXA or MV, but I think MV has it too.
You will want to config it like this:

Info is the other variable you created, the rest is obvious
Now you just created an event that checks coordinates. To use that practically, is simple:
Create a condition branch checking the Player/event X and Y coordinates, the numbers to imput are the same of the map's X and Y coordinates.
For example, in the same event that lets the player jump (common event or not) right before the jumping put a conditional branch like below checking if the player is in a position that would lead to his "death", if so dont let him, with a message for example.
If he dont match the coordinates, let him jump normally (on the "Set handling when condition do not apply"
I hope its easy to understand now
