Okay.

About Stagecast Creator: It is a "programming language" designed and oriented towards children, which has a VERY simple interface but powerful functions

It is basically the Scratch of 2007 :-)

and why did I decide to make a game in such an old engine?

For two reasons:

1. To experiment
2. And because I can't program a single line of code

since Stagecast creator works with simple and basic rules that with intelligent use can make interesting games (simulations)

Which gives way to Dungernox
