Difference(s) between demo and payant version ?

Hello everybody !
All is in my title...
I research it on the net but there's no precise answer to my question simple yet

The difference is that the compile / build game feature is disables & that you can only create 10 scenes with the freeware version. Other than that, it's entirely the same.

Okay thank you very much !!!

Is there a french manual if i buy the indie version ?

Unfortunately not. There's quite a few French users on here that will probably be willing to answer any questions, should you need help.

To be honest there isn't much of a manual in general. I believe there's a pdf manual of sorts that comes with even the freeware version, but I can't remember if it's German only, or if there was an English version available too. Either way it doesn't cover much. We have this forum & the wiki too, which you can use for finding answers / requesting help. Eventually the wiki will be where all the manual / documentation will be located, but I've not had the time / inclination to work on it for a while & I'm waiting until the release of the new GUI version of the editor.
