Sorry, I had to use an article for more HP. Anyways here's the update:

Using the Scratch GameJolt API plugin,(https://gamejolt.com/games/gjapiscratch/530359) I can now implement trophies into my game (Note: The trophies only work if you log into your GameJolt account, that'll be an option in the settings. If you don't log into your GameJolt account then there will be built in achievements in the game.)

The built in achievement rule may or may not apply to the Undertale hard mode game though. (Reason being, I had coded the achievements for KVN before I found out about this plugin.)
