Using Hoarcekat as a framework!

Hi everyone I really, really need your help in this mystery.
Am trying to use Hoarcekat as a framework for my game but the way I want to use it is that I want to use it as an alternative for play solo, so instead of me testing the game I can just use Hoarcekat like Rawblock - https://twitter.com/Rawblocky/status/1498875304378466306/photo/1

I would really, really appreciate it if you can help me!
