First, just install the version with the highest label (right now is "YYC 20240617v3" (YoYo Compiler 2024, june 17th, Version 3)) It doesn't really matter if you choose VM (Virtual Machine), or YYC (YoYo Compiler), but most of the times YYC is faster than VM, other than that, they are the same.
And, if you feel lost, look around this forum, there is a few guides or some things similar to guides, but they can be helpful on some way.
Just remember "Think, Attempt, Repeat", most of the puzzles can be solve if you think outside the box or think on some weird way to get though it.

More than that, just remember this is a game, a puzzle. Made for entertime you and make you think or enjoy, don't push yourself to something like "i need to get every achievement possible!!", because there isn't any.
The game is in develop, and you, and all of us, just need to keep that on mind.
This is a game. Not a list of things to do.
Now go, and enjoy your free time.
