Hi everybody !
Thanks for the support, once again, it makes me feel that I must put my wife in a closet and schedule some vacations in order to finish my mod faster

!
I'm trying right now to put on the (numeric) paper a planning leading me from now to the release, and I will share it with you when it's done (edit : done !).
Azel,
marten_1992 and
Slayer82, I keep your names for when the beta-testing will start. I my opinion, two or three commited testers is enought, but if new supporters arrived and sign on I will not threw them away

!
Honestly, right now I have 14 levels left on the line to put the mod in a "finished" state. When this will be done, I will review all levels to increase the overall "decoration" (improving lights, putting more grass, and some actions like that). Then, I will start a full playthrough to fully test the whole thing (I tested all puzzle continuously during the creation, but I need to test them in global context to fully validate them).
After this playthrough (or during it, depending of the amount of bugs found), I will put one or two people on it with me (family mostly) because as the creator of the mod some issues will not be seen by me. Think of it as an alpha-test.
When these people had finished their playthrough, and only at this time, I will use the community to beta-test the mod.
It's only at this time that I will need you 
!
The con of this approach is that you will not be able to test this mod until this summer (probably), but the pro is that its overall status should be mostly OK when you will put your hands on it.
I planned to use a shared Excel file to centralize all the bugs report and the fixes done, but I will tell you more in due time !
Once again, thank you for your kind words ! Now I feel a lot under pressure, I (sincerelly) hope that my creation will give you as much fun that I had designing it and creating it.
PS : english errors will be part of the bugs report, because I'm aware of my (bad) level in english and I don't want to give players a full-of-mistakes mod !
By the way,
UPDATE
- New level finished (29/43)
