Some suggestions for improvement:
*** The graphics. Note how the background has all these small bumps left behind from when you drew the asset. If you're using vector graphics, you should be able to edit the dots so it looks smooth and perfect. Work towards that.
*** Add a menu screen. When you click the green flag, the game starts up without warning.
*** Lox's hitbox is massive, making it very difficult to dodge bombs.
** The score and lives are displayed using Scratch's built-in variable display. A custom UI would be recommended.
** Lox, the coin, and the bomb all have only 1 frame of 'animation' that's very poorly drawn. Work towards not needing to use basic shape tools as a crutch for limbs, feet, heads, etc. This may take some time, but it's worth it.
* You don't need to mention that "Background is Dark Blue and Lox is Purple". I and most other players would already know that Lox is the player character.
* Maybe don't capitilize every single word in the description.
Hope that helps. For additional game design tips, I also recommend any one video from Masahiro Sakurai's YouTube channel.
