I made a web game to practice country locations a while ago and HN liked it, so I thought I'd post my updated version as well.

As for how the game works and feels, I'd really recommend you checking it out for yourself, it's free, no signup, no ads.

The tech stack is Vue + ts + Tailwind/Daisy for the looks. The learning algorithm is a slight modification of the ts version of FSRS.

If you have anything to add, it's open source as well (https://github.com/koljapluemer/learn-worldmap), although not well documented yet.

In the end it's just a little sideproject, but I hope you enjoy it — any feedback welcome :)
