I've had a fair amount of fun playing with Unity, but in all honesty, I haven't progressed far enough to make it worth the switch.
I'm at the point, now, where I really need to make the big decision.
Making the complete switch to Unity will require heavy work, recreating my entire framework, and getting everything up and running smoothly enough that I can rapidly cobble together AGameAWeek.
And it's the "Rapidly cobble together AGameAWeek" bit that puts me off.
At the moment, and I'll admit I am still trying to figure out this whole Unity thing, I appear to need to perform about 4 or 5 steps to add a single spritesheet into the engine.
Adding it to the Project, cutting it in the IDE, adding it to the Object, and then defining an array to handle the individual frames within the sheet.
I know that's "not a lot", and my experience with AGameAWeek thus far have taught me that things like that tend to get easier, the more you do them and get used to the way they work.
..
But right now, I'm not sure I want to be doing that.

In Monkey, I add the file to the folder, add a single LoadImg() command, and then it's ready for use. Unity's more about clicking the mouse, than tapping the keys.
Does that make me sound lazy?! It probably does.
I dunno!!

So, for the past 24 hours, I've found myself slipping back to Monkey, and fiddling about with my framework.
I've been experimenting and testing all manner of odd little things, and wondering if the whole Unity thing is worth it.
I'm still on the fence, but appear to be heading back to Monkey.
