It's really hard even with coporate experience. But given that OP: 1. already had gamedev experience on top of tech experience 2. kept his technical scope very low for his assumed skill level (2d game, Godot engine for fast iterations, full-time focus and scheduling) 3. Was relatively stress-free in terms of his personal situation I can understand a pretty smooth development period.
