That's nice some users are still active with that.
I never tried it, but I guess having C2, I shouldn't go back to give it a go. right?
If you have C2, you probably won't need Classic but since it's free and open source there's nothing to lose by checking it out.
Keep in mind it hasn't been updated in ages and can only export Windows EXEs. It's originally what piqued my interest in Construct/Scirra. It's buggy and somewhat incomplete compared to C2&C3 but I still love it.
