Cute game! I thought it was really cool how the levels were randomly generated. It took me a while to realise that the ammo reloaded, I was trying to conserve it for ages haha. It was a bit hard to tell whether I had shot down enemies or whether they had damaged me, since they vanished into thin air either way. Perhaps an enemy death animation would be a good form of feedback for the player to know if their shot was successful or not.
