Why the heck should anyone be impressed that some dude took 6 years, and tens of thousands of children's dollars, to release not even a full game but a simple demo, and the demo itself is riddled with bugs, crashes, and "placeholders", among others (and putting aside the fact that the game is poorly designed from the ground-up so that even if you got rid of these errors you'd still have a subpar product).
I assume you are a literal kid, in which case I tell you that Alex is not the type of person you should feel "proud" of, and you'd better look for other role-models.
