From now on, I'll try to release a new update about every week or two until the game is released! For this update, I introduced a new enemy type, the Shooter (very creative). It only moves horizontally, shoots continuously, and tracks the player. It is featured in the second level, which has been introduced in this update. The new level is also double the length of the old one. I also added some other stuff too. Here are the patch notes:

Additions:

-Added a new enemy: "Shooter"

-Added a second level featuring the new enemy type

-Added flashing effect when enemies take damage

-Added a stats screen at the end of the level which displays the current score, total score, and total kills and allows the player to continue to the next level

Fixes:

-Fixed UI issue where the health bar appeared on top of the tutorial images

-Changed the color of mine bullets to better contrast with the new background

-Fixed issue where the player could continue shooting after death

-Fixed issue where the player could activate the pause menu while in the shop which soft-locked the game

-Fixed issue where, if spread and mine were bought, then the weapon detection wouldn't work as intended
