Really impressive game for 10 days. Gave me a lot of ideas and honestly pretty solid game feel.
Feel like it might be a bit more exciting in the beginning if the enemies had less health but there were more of them.
Also, I might be missing intended gameplay but there's something really unsatisfying about the scrap for the level progression being shared with the gun purchase mechanic making it so the first few levels you don't have the choice of saving for a better gun. Maybe being able to progress waves without depositing scrap or something could feel better.
