Fun little game! I wish there were more reasons to move though. For me the optimal strategy was to load on ammo and stand perfectly still and shoot if something came my way, which meant most of the time I was just watching my ship float forward. Still, it grabbed my attention for a couple runs! Also, it would be nice to have the shoot keybind in some key that does not conflict with the movement buttons (pressing forward and shooting at the same time is not very nice with the current keybindings). Spacebar would feel more natural.
Well done on the game! Good Job!
