Remaking this exact game on your engine of choice would actually be a great starter project. It's extremely small and self contained, very little actual interaction, simple models and whatever textures you can make or steal.

Yes, but the AI will handle asking you everything. Here's how easy it is to make a game that functions like his but without the polish - put Claude in plan mode 1 prompt, then answer any questions it has:

--- Make me a threejs game in html. The "game" is where you can tap a button to add a log to a cutting block. You have an axelike (e.g., a stem cube for handle and slim cube for axe blade) object that you can axe into the wood, and wherever the head intersects the underlying "log" cylinder it splits the log.

So blade is a hittest object, where that object hits the spawned log, the log splits, use a decent physics lib (ammoJS is fine) so it feels good. Do you have any questions? ---

After answering about 5 basic questions, the above made a cute little physics based log cutting game very similar to this guy's demo - now it'd probably take about 5-8 more hours to slowly prompt out a more polished version. This stuff is really easy - you don't have to have any experience in game dev to prompt it up.
