In the official FAQ, the developer said this:
Will the game be made available on Linux?
Perhaps, if you’d like to increase the likelihood we will do this, please register your interest in this thread and add the game to your wishlist.
The thread is actually closed, so you can't comment there. However, there is another post asking about Linux support so I suggest you post in that one if you would pick up a copy to play on Linux.
Honestly, it looks like a huge amount of fun. The developer is releasing multiplayer soon too and it's likely a game I would happily play.
- Epic Voxel Dismemberment: In addition to looking cool, the ability to cut off body parts is central to the gameplay. Jumping on one leg is a common occurrence. Large enemies need to be cut down to size before a fatal blow can be delivered.
- Sharp Sword Combat: Combat is fast and intense, putting great emphasis on movement, timing and positioning. You are never safe, as any blow can instantly kill or dismember.
- Entertaining Commentary: With over 10000 spoken words, Commentatron and Analysis-Bot provide a running commentary of your performance and react to your activities.
Thanks for the tip, NuSuey!
