Many players who have experienced the game share your concerns about the speed of the enemy bullets. Unfortunately, I didn't have the opportunity to put the game through a proper play testing process. As a result, while developing the game and playing it repeatedly, I unconsciously adapted to its fast-paced difficulty (I can comfortably score over 50 points now :D). There are actually three types of enemies in the game; if I remember correctly, you should encounter the second type after reaching a score of 20. Thank you for your feedback!
