This was enjoyable! Typing to start sets the stage, and what follows when things begin appearing is intuitive. The visuals are clear and fun, too. Difficulty seemed to escalate rapidly in the mid-to-high 40s...I noticed your comments on this in replies to other posts - makes perfect sense. (On my end I simply need to improve my typing speed, haha)
Fun as a stand-alone creation, though I'm definitely interested in seeing where you might take it if you expand on the concept - well done!
