This is the kind of game Zachtronics would make, which is a glowing review in my book 🎉 That said... I think that for us less-musically-inclined people, having a few more tools to help diagnose what's going wrong would be really helpful. Here's a few ideas:
- Being able to adjust the tempo, so I can hear things at a more comfortable pace;
- Keeping the goal card on screen at all times, and maybe even including a little dot that moves along with the beat when you hit the play button;
- Having the speaker emit a green note when an instrument reaches it on time and a red note when it arrives off-time (or some other visual indicator of your timing success, since adding colors might clash with the beautiful color scheme!);
I'm sure there are other ways to help indicate success/failure, but these are a few I could think of. While I couldn't finish the game on my own skills, this has the bones of a great game. Stellar entry! ⭐
