Very well made game. It's fun when the solution falls into my lap, which happened often in the early levels since my choices were limited, but finding that solution comes down to a lucky guess (a roll of the dice if you will) when the possibility space branches just a couple of times. The gameplay is essentially trial and error because it's not feasible to plan more than 1 step ahead. I don't feel like I have the ability to find the solution through thinking alone.
The sound effects add a nice emphasis to the steps. Makes me wonder if there are more "mnemonic" melodies or rhythms that can be associated with each number. Not explicitly suggesting this but an anecdote that comes to mind is the idea of rhythmic solfege, which associates different sequences of syllables with different rhythms (say "ta-ki-ta" for triplets or "ta-ka-di-mi" for a group of 4 notes, etc.) A melodic approach might be:
- root
- root-fifth
- root-third-fifth
- root-third-fifth-octave, etc.
Or maybe there is a pre-programmed song in the steps and the player essentially controls the pacing of it through the act of walking to the goal, which would add some tension and release to the gameplay, increasing the satisfaction of reaching the goal. Anyway, neat submission.
