Very cool. Nice release.
And I think people have tried this before, but Construct seems to run in Wine on Linux. Some UI bugs, but the editor seems somewhat usable. Can scroll around in the Direct3D viewport (layout editor), select objects, modify properties, etc.
Unfortunately it crashes when I try to view an event sheet. Looking at terminal output, it's probably due to incompleteness in Wine.
Apps and games compiled to .exe's run just fine so far. Haven't tested Python scripting with that.
