I have built a game that combines popular rogue like mechanics with language flashcards. This way you can effortlessly pick up new vocabulary.
To play: build a deck of super cards, and flashcards. Build combos playing around letters in your cards and score big points.
A year ago I played a very popular and fun rogue like deck builder. I thought "I wish language learning was this fun". So I started this project.
The game has a free playtest open for anyone to check out.
