Great idea!
This give me an idea for touch typing training tool I’d like to make.

Cool idea with such a great potential! I'd suggest to rebind navigating to Shift+WASD (Shift — directioning mode, WASD — choose direction, optionally — vim-like navigation). This will allow player to keep hands on the alphabet section of the keyboard. Another way is to somehow limit the randomness so that the letters around the player's cell are always different. You could also +scores for correct inputs and -scores for incorrect ones. And if the letters you enter form words, player get even more +scores! Then you could introduce different backgrounds for the cells, which would provide different bonuses, like in Scrabble. And then you could make all this greatness PvP as well. :) C'mon! Go on! You could turn this prototype into a very cool typing game!

Nice start to a typing experience. I like the typography look and sounds. The typing animation is smooth as well. Nice work.

Would like to see a goal or target set for the player. This is a rich design space, interested to see you develop further.

Loved the idea, would like to see scoring and some sound effects.  Could be a great typing practice game with some work.  Good job!

Cool idea! Simple for 48 hours jam and yet powerful for extending into larger game with exploration.

Great game! Simple but fun!

creative entry. the camera cant keep up if you start typing too fast. well done

A fellow game about typing, I like it :D 
Some kind of score system would've been cool!

Orignal idea. Not sure I undestand the goal of the game though
