Not a problem at all, however if I recall correctly, you already know Unity, so if I decide to use this tool instead of C2 while I'm waiting for C3, I don't think my opinion will be really useful for you. Nobody uses Flash anymore, so once again, my point of view about it would be pretty useless. If I use Haxe Flixel or Godot or Fusion or anything which is not Unity, and if you wonder how useful and powerful the LibGdx library for Java truly is, I'd be glad to shate my experience on the matter, yep.
Indeed, I tried Unity, but I found UE4 more suitable for my needs. Currently I'm learning Godot. Not that I want to leave C2/C3, I just like to keep my eyes open on the market. However it's always useful to see this matter through someone else's eyes.
