I came to smash some keys and I was not disappointed! :) 

Though funny story, I forgot I had a paused youtube video in another window so when I hit spacebar while key smashing, the video started playing and I thought it was narration to the game. I was like... is there gonna be a calming narrator talking about relieving stress while I'm smashing these keys xD 

Anyway, concur with everyone else, simple but great at what it does. The interface and aesthetic are great! If you ever feel like expanding this into like an actual game to teach typing, it'd deffs be a hit. You could even keep the key smash thing in after the typing test is completed... RELEASE TENSION IN THE WRISTS! SMASH THE KEYS!

Nice work!

The feel and aesthetics were really nice, like the feedback and visuals when hitting a button.  It was kinda interesting when you start to actually map your whole keyboard layout as you type (or roll your hands over the keys :D).  There's not much to the game but that doesnt mean its not pleasant, and I think you achieved what you set out to do, so good on you.

I really like this game! :>

A bit hard to figure out controls/what to do at the start, but an interesting concept. Would be better if there were some kind of levels(with words, maybe sentences to type?) or something else. 

Good job! :)
