The UI effects were well done. It definitely added to the overall theme of the game. I did have some issues with figuring out the game. The shooting did not seem to do much, and I was never sure if an enemy was hitting me. Some visual feedback would help tremendously! I also wasn't sure what the pickups were doing when I got them, and I had a point where my health read "$#%#^ Error" and I wasn't sure if that was intended or not. I do like the minimalistic graphics for the player and enemies. The flickering enemies were also interesting and well done. Thanks for making this!
