Not just for platformers - a monumental achievement! brilliant WYSIWYG editor, intergrated physics - the works - I love it! I note the use of a GUID for each object so... perhaps you're planning on synchronizing across a network / offering multi-player functions?

Fantastic! although I'm biased as this is more or less what I've been working on but in 2D and more production ready

Since we face many of the same design challenges perhaps we can exchange ideas one of the days? might make both our systems better for it?

Keep up the excellent work! there's a lot of great engines but having a workflow tool like this to create content and debug game-play makes your engine the best choice by default - even if another had more features it wouldn't matter as your system clearly shaves off a bomb load of development time
