I scored 16000! It was fun to give it a shot!
I think something that would be really easy to improve on the look of the game would be to set the filter mode on the import settings for your sprites to "Point (no filter)" which will keep the pixel art looking crisp!
I also think it should get harder a little faster! It would be pretty easy to reload the game scene when the player dies as well to allow the player to keep playing!
Good job getting something submitted!
