It's not at the moment.
It has been suspended for now, probably until Construct 2 is available for public release.
I will use all of the code and ideas though for any future development, but there are some things that will be available in C2 that simply aren't going to make it into C1 which I would like to implement into the game.
Workarounds are sloppy and annoying... so it's better to just wait at this stage I think.
Currently working on a simpler idea for a more basic game which in theory should be much easier to work on.
