Are there any hacks for stick adventures online and what are they

No. It's impossible because all the variables are server sided. Meaning that every thing is stored on the host.There are two ways to avoid this:

1. Go to uni, train in computers, then hack him.
2. Find the owner and threaten him till he puts up your stuff.

Option 1 and 2 are not recommended.

So...
Sorry for the disappointment.
