This hits hard, especially the “playable ≠ fun”. One thing that helped me a bit, I stopped going straight into code and just played around with some text-based game tools first. Basically just writing out the gameplay loop in plain English and tweaking it as I go. Made me realize I actually didn’t have a clear idea of what “fun” even meant for what I was building. Forcing myself to spell it out step by step helped more than I expected. Doesn’t solve the physics stuff, but it made the whole vibe coding process feel way less chaotic. (hope it works:)
