Super interesting take on the count down theme; even though it's a time-based countdown, you need to keep track of lots of different tasks at once. I found it helpful to stare at the board for a bit before starting so I could mentally "queue" what I'd need to press. I did seem to find a bug (or maybe just a keyboard issue for me?) where my pressing my "H" key didn't actually affect anything in game.
Also, I super appreciated the tutorial that split everything into bite-sized information with visuals! I found the all caps pixel font a little hard on my eyes for big blocks of text, though.
Overall, a fun game that reminded me a little bit of the typing games we used to do in school!
