You should make a repository thread with all your tutorials, that'd make searching for them easier in the future. Also, maybe it's a good idea to prepare your art assets beforehand and link to them as a separate file. You're teaching how to set up the game, not how to create sprite art. Besides, you'll have time to create detailed sprites.
Other than that, very nice tutorials you have made so far. I'd consider using Construct if I wasn't such a code junkie (as GunZet can confirm...)
