This week I was pretty busy but I had to implement this idea before I forget it. I decided to create a score multiplier that activates when you play at the top half of the screen. The higher the score, higher the level of difficulty. As well as that I added a 'BlockBreaker' power up that allows the player to smash through a layer of blocks without dying at any time. When the gun shoots a box it shows how many hits until its dead, in the future I might try to reverse this feature and see how that plays out.
I have a few issues with a few mechanics i've implemented such as the power up spawner because the power up can put a box out of place because of its collider.
