Moving from web dev to game dev (as a hobby). Any advice ?

Been in web dev for about 10 years, and always wanted to switch to game dev. I’m thinking of starting as a hobby to see how it goes, probably with something simple like a vertical shooter.

Mostly curious about the transition from web architecture to game logic. For those of you who have done both:

1. did you stick with JS engines (like Phaser) or move straight to something like Godot or Unity ?

2. what was the biggest mindset shift coming from a web background ?

3. is it better to keep it simple and focus on browser version as first couple of projects ?

would love to hear some opinions
