Just a mini-guide explaining the "Version" variable a bit.

Versions:

-P.Craft is the first release, found on Lexaloffle: https://www.lexaloffle.com/bbs/?tid=3200

-P.Craft Deluxe is the version on sites like itch.io, and is also the downloadable version of the game. It added a boss fight, talisman, and a map: https://nusan.itch.io/pcraft

-Stranded Isle is the version found on places like Coolmath, and is technically the most recent version, but it's not very different from P.Craft Deluxe: https://www.coolmathgames.com/0-stranded-isle

-The MelonkeepR Mod changes all drop rates to be their max, and is a mod of P.Craft Deluxe in particular. You can find the download for it in the Resources tab.

-Pog Edition v.0.9+ is a mod of P.Craft created by me which offers alternative sounds, music, and also makes the text a bit more natural. (ex. haxe is just axe.) It's available in the Discord server, or alternatively you can DM me and I'll send v.0.9.2 your way.

Differences:

-P.Craft and -Pog Edition don't have to load at all, making seed grinding trivial and timing a bit more simple. However, you obviously can't run Boss Kill% with them, as a boss doesn't even exist, and the absence of a map makes verifying No Land% impossible.

-P.Craft Deluxe and Stranded Isle are practically identical, and whichever you play between them comes down to preference. If you want to play a downloaded version, however, P.Craft Deluxe is your only option.

How to Tell Versions:

-Title screens are the best bet, and the easiest way to distinguish them. It literally tells you which version it is.

-The pause screen looks different between P.Craft and P.Craft Deluxe/Stranded Isle. Only P.Craft has a semi-transparent black background, as the other two versions just have a solid black one. The options in that menu are also different; note the "Options" and "New Game/Save Game"

-When fullscreened, there's a slight difference between itch.io and coolmathgames - those things at the bottom of coolmathgames that are "Exit Fullscreen" and the level EXP bar are not in the itch.io version. (obviously) There's also a difference as for where it puts the game: itch.io snaps it to the top middle, while coolmathgames keeps it near center middle.

-If everything is dropping max drops, and the drops aren't varied at all, then it's obviously the MelonkeepR Mod.

-While -Pog Edition is hard to detect visually, audibly it is much different. Music is changed, sounds are changed, etc.

What's It Matter?

-Play the version most comfortable to you. P.Craft, and its mod -Pog Edition, are easier to seed reset since there's no cart swapping, but they don't allow you to run categories like Boss Kill% or No Land%. Deluxe and Stranded Isle don't have any gameplay difference, however one might not work as consistently for you as another. The MelonkeepR Mod is only to be used for Dream% runs, so if you don't like RNG that much you can always go with that.
