Damn. I've had this exact idea running around my head for about 10 years, and even started building it in Unity. But I'm a programmer not a game designer so I couldn't flesh out the mechanics to make it fun, or find someone with those skills to work with me. I haven't played this yet but it looks like you've achieved that, congratulations! It's cool to see pretty much exactly what I envisioned in my head come to life (he says through gritted teeth...)
I admire your 'pay-what-you-want' model, I do that for all my C64 releases. At the same time I don't think anyone would begrudge this being on Steam and reaching a much bigger audience. After all, if you haven't got $10, you probably haven't got the PC capable of playing it....
