I agree. I'm not a game dev. I had a game idea and vibe-coded it with Claude. I kinda got what I had in mind but the game is just not engaging. I don't even know what to prompt. I tried "how could the be made more engaging" but no good ideas are falling out. I just have a lack of intuition for this kind of development. And Claude doesn't help.
On the other hand it should be so much easier to port full games to mobile. For example Stacklands is a game that would feel right at home on a iPhone or iPad, but currently it's not an app I can download and play on a bus.
