I had that same reasoning attempting to learn Godot through this Jam. Unfortunately that was too big of a challenge for me. :P

Hearing Love2D being brought up a bit around here, is it easier to learn than Godot for someone who's new to UI/physics programming?

I haven't tried to learn Godot, but it's on my list to look at. I found LOVE very straightforward to pick up, mainly because there is good documentation, and due to the nature of it, you can rummage around in other people's public .love files to learn from them.
