我感觉可能只是单纯需求比较少，大部分 ruby 的场景可能用不太到

国内更多是做 rails，一般用不到这个 gem

一切以需求出发

I totally understand your concern about promoting your gem—I've also developed open-source projects and found it difficult to get noticed. In my experience, actively sharing your work on platforms like Reddit, dev forums, and even creating a simple tutorial video can help a lot. Also, drawing inspiration from how games like Monkey Mart are organically discussed in online communities might offer ideas on genuine word-of-mouth promotion.
