Thanks! Well, the bomb particles are active physics, and deal damage, so they can hurt the cat, and you can also use bombs to launch other bombs - but that's about all at this point. :-D I focused mainly on just learning the basics, and getting my usual "perfect pixels with native resolution positioning" going (the way I do it in Kobo Redux), because I wanted to make sure Godot can deliver the kind of smooth player experience I want. And, clearly, it can! There are some minor issues and messy areas, but overall, Godot has been a great experience so far. Might use it for non-game dev as well, as it's actually a lot smoother to use than traditional GUI toolkit solutions, especially if you need to go beyond the basic controls. I'm wondering what it would take to integrate it into VST plugins and the like...
