I second godot: easy to develop with, easy to make GUIs (or complex text-based layouts).
The exported "executables" are pretty small and performance is acceptable for small mobile based projects.
Nice to hear your history.
I'm very interested in the details of your transition (pros and cons).
Are you from Brazil? Can I send you an email for a little chat?
