I would totally play this again with a chart. Even if it was a companion image I could have open next to the game!
It was fun, and the chart will triple the fun!
Honestly I might sneak that in the description. I know this is gonna be the third time I somehow find a way to loophole Harold Jam but if I threw a little cheatsheet in the description or the comments then I think it would do more help than harm. With that said, the next step is to design games so you won't need a cheatsheet, and I think having a normal length game instead of compressing it into a jam may help with that.
