Great to hear — Kotlin is wonderful!
The Koans are a good start, but for me they still felt like “exercise” instead of playing the game for real.
Certainly there are cases where you need to do the drills and the exercise to have some sense of what you’re doing, but when you get down to it, playing the game is what’s really fun and will keep you motivated.
So as soon as you’re feeling up to it, start writing real code! :)
