If you haven’t yet, start with the tutorial level here: oncyber.io/tutorial
Token gated? You’ll need a token from the "oncyber community (eth)" collection to access the tutorial level — that’s the first gate (and a mini-tutorial itself).
Any oncyber community gallery will do, and many are very modestly priced — however, if you’d like to directly support a weary hopefool in his mad buidlin’ efforts, you can purchase an edition of my first minted gallery template, "The Caverns Below," developed at the MetaArchitects HUB community over a period of several months.
