i made my mouse cursor a knife so when he steals it from me it can be like the actual untitled goose game. he also has a minecraft plains background for him to roam around in. 
go to any mouse cursor website i use rw-designer.com and just type in knife in the search bar and click what knife you want. download the file and put it in a folder to go back to later and go in to your settings and find your mouse settings. click additional mouse settings and click the pointer tab click browse and open the knife cursor file. click apply and ok and it should work!
