Unfortunately, no screenshots. But I have an update nevertheless!
I added a lot of gameplay, including the final, but not concrete, design for the level generation system. I also fine tuned the controls to the point where I am happy with them, along with adding controller support. I made sure that the 3 weapons in the game work the way I envisioned them, along with balancing them for what is in the game currently.
I added three enemy types as well. I have crawling enemies that move along the sides of the level on the walls, a flying drone that shoots your from above, and mounted machine guns on the walls that will fire in a straight line towards you.
Again, HOPEFULLY I will make time for screenshots so that you can see how the game looks at this point.
