@endel, for the most part, the only difference between Construct 3 and Construct 2 is how it handles The Aces(Actions, conditions etc) the runtime is 1:1 with construct 2(Construct 2 uses a custom google closure compiler set to advanced mode tho so anything ES6 related breaks the minify/optimize process) so the only work I did was go thru the aces data from construct 3 and translated it back to construct 2s edit time API

Ported https://github.com/gamestdio/colyseus-construct3 Back down to Construct 2 cause at this time Construct 3 isn't stable enough for full production use and is lacking a lot of useful plugins.
