I like the simplistic art style, makes it look quite inviting for sure. Looks like a game that's easy to get into, but likely hard to master.
The developer said this last month in response to a request for a Linux version: "I hear you, and as Elias said, this is something I will pick up. I cannot give an time frame, because I want the mac build to be ready first. More people have been asking dor it, so far. But I suspect that once that works, the Linux build isn't too far off, either. Its more or less the same technique to compile for another platform."
With that in mind then, hopefully a Linux version won't actually to be too far away.
