I'm noticing a few odd votes on my game too, with strange justifications. It might just be the community though, I've not been there before now.
I think future competitions could do with some much more concrete guidelines. Not just to better explain that votes from other users account for nothing, but also how "updates" work. I've just read back through this thread and seen people are continuing to work on their submissions after the deadline, not just with bug fixes but full-on content updates and mechanic tweaks. Doesn't that defeat the point of working to a deadline? What about those of us who worked to that deadline and then stopped - now we're learning that we could have continued adding content that we had to cut last minute, and further polish our entries?
At the end of the day, I entered for the experience and to push myself out of my comfort zone (fantasy-based settings). But for future competitions, we definitely need to set some more rigid rules, because I'm now completely confused about the point of a deadline
