Scirra isn't going to steal users away from Unity and Godot easily -- but they can get the RPG maker community easily. There are very few RPG maker based games out there and yet they have a great many users who only ask for a non programming environment -- with with with ... a decent set of starter graphics and sounds.
If you say your strength is to make games without having to program then spending lots of time on tweaks to the JS script is a poor use of time compared to getting people who want to make games without programming with some packaged assets and solid expandable examples that do the dungeon crawl or space opera.
It would take a month, some portraits and some tiles.
