Nice game!
I didn't really understand the scoring system. Trying to hit the moving target felt a bit unresponsive, i was never sure i actually hit it. Since the dart didnt move along with it i assumed i hadn't, though i did get a few points.
I had pretty much no issue dodging obstacles on the way to the board, although i had some issues with depth perception. It's quite a fun experience when you do hit something though. It doesn't feel frustrating at all, which i think is a great sign.
This is definitely an idea worth exploring and maybe polishing it for a full release :)
