Not very stable at all, but the cli game (wordlec) is playable with the responses of whether you hit a letter or not, the naive solver and the stupid solver work too.
However, I expect that the API will change a lot before v0.1. I will release it when I deem it somewhat stable. Happy to hear you like it.
I hope the first one. But the effect is real, stuff you know already was easy and stuff you don't is hard. I'm feeling it with my migration to proxmox, it's hard.
