I hope you do. I like the game and I wouldn't mind paying for it, but right now the browser is the only way for me to play. Considering that you have an Android version already, it means that your code is multi-platform ready as-is, so I imagine that releasing it for Linux/Mac shouldn't be a big deal. Of course, you will have some extra overheads to think about (dealing with potential other platform bugs), but it shouldn't be too much of a problem.

Yeah, you're not the only one under the impression that multi platform is not a big deal, but it has a much larger rats tail than you might expect. We tried building for linux and mac and were met with a host of issues that we did not have any immediate solutions for. I understand that for mac, the browser version is sadly your only option, but for linux, you can just any of the compatibility tools to play windows games.
