Nice graphics!
I ran into a bug though. After dying and pressing retry to restart the game, the level seems to reset but no enemies spawn, nothing happens, I'm just flying through empty space. Interestingly, returning to the main menu then starting a new game does not fix the issue. Each attempt I have to refresh the webpage. I'm using firefox.
This may be a design choice, but I also noticed that when I fly up and shoot, the bullets don't fly straight forwards but up at an angle. Is this intended? It doesn't happen when flying down.
