Hi! I noticed a special feature in your game: the speed of movement of the player varies depending on the direction of movement of the player. This may have been intended on purpose, but if not, then the situation can be corrected. Now the player's horizontal and vertical speed is standard, but when he moves diagonally, it increases twice. To fix this, you need to check the current speed and do not allow it to exceed a certain value. Thank you for your attention to this detail. I hope that in future update...

The small bullets is little hard to see coming, try color them brighter color, they are nearly inadvisable to see. It fun game, but I can't handle multiple tiny flying bullets.
