I tried HRM after playing a decent bit of TIS-100, and the interface was just too slow and clunky in comparison for me to keep going. One of the more brilliant aspects of TIS-100 is that you can always see the full program on the screen at all times, and part of the challenge is to refactor code by physically moving it around the screen. HRM in comparison only displays the code as a list of commands and I found it frustrating to navigate through, especially for big programs.

Another really satisfactory part of the gameplay of TIS-100 was that I sometimes came up with a new optimization to solve a later challenge, and could then go back to my old solutions and get large speedups by applying the same optimization there. It made me play the game nonlinearly and go back and forth between the challenges and trying to improve my code in them. It's just a lot of fun for programming-minded people.
