Ayyy, this showed up in my queue!
Finally got to try it for myself, and definitely needed to scroll through the other comments to understand that I needed to press Enter and type commands myself. On my second time around, I did notice the tutorial for that appear at the top, so I'm thinking it would be good to shove the tutorialization in the player's face more, especially for the "tutorial" levels.
There's definitely a fun feeling of being a hacker here, and I can see the potential if the complexity of commands and stressors like time limits and life counters get introduced! Overall, it is SUPER smooth and stylish~
