Cute game, I absolutely love the art style for the enemies and their animations! 5/5 on graphics. Final score was 1460, but i realized that the score didnt reset on death :( It was nice having some slightly different enemy types, but some that shot at you might be fun, and awarding varying points would be good too. My hand is also very tired from all the clicking, maybe some kind of hold-down firing would be a nice respite for my wrist :)
For arcade games like this, i like to recommend what our team did, and use the LootLocker SDK that lets you easily host leaderboards online for games like this. Super simple to use, just need an API key, and then call an endpoint with score and username/id. Would love to see how I compared against others!
