Undertale Tower Defense

Can someone make a new GUI script for this game? Maybe a "Gain XP/Souls" or "Gain Units", then you can pick what Unit you want, for example if you need mettaton NEO you can select it and equip it. And maybe add so you can get every title and instakill monsters.

i want this script to work only when you go in a match/round like Ruins or something.
