Nice game! I thought that the value in my circle will be added to the score multiplied by the value of enemies (and always destroying all enemies in range). TBH it would be a neat mobile game if done like that :)
Thanks for the feedback, glad you liked the game ! It's not a bad idea, I focused on the theme by increasing the "damage" and then the enemy life, but it seems funnier in your way. Probably a future update after the jam's end.
