Interesting, though you seem to be going for a "no coding required" approach which always ends up hitting limits pretty quickly.

Do you support an easy way to add custom JS code for logic that the in built tools cannot handle elegantly?

Also interested in how this works, do you generate JS code or do you have a JS engine which reads settings from other files?

There aren't any hard-coded limits, and you can do things like make recursive functions with unique local variables at each call. We have a JS SDK for custom code too: https://www.scirra.com/manual/15/sdk

I've used Construct 2, it's definitely good stuff.

Do you plan making a linux version?
