Yeah, we'll add a repair function at some point. When we do I'll fix this!
Viewing post in Eric you should fix this
I have a suggestion regarding the repair function
Since I believe I saw you say something about planning to implements pick ups/power ups at some point, how about making the larger enemies or mini bosses drop something which will repair one or few random voxels and possibly restore function to a missing limb. I'm guessing this would be hard to implement in a way that won't result in floating voxels though.
