As you can see when starting the game, a cluster of graphemes appears on screen. So does a word said by the cat. Translate the word into Finnish using your glyphs, lest you lose. You can move your graphemes using keys A and D, or rotate the configuration using keys W and E. Finally, you can request additional graphemes by pressing your space key. Please use the nominative singular, or the ("first") infinitive (i.e. the one that isn't a converb), whichever is applicable to the current lexeme. Otherwise, the computer might not notice that you have created the correct lexeme.
Words are allowed to wrap around and continue on the row above (not on the one below, mind you). This is a feature, not a bug. The reason why it is not a bug is because I am lazy. Disclaimer: This is a very terrible way to try and learn Finnish, since it only teaches 5 words. The original hexagon costume was stolen from https://scratch.mit.edu/projects/318837312/.
