I love the theming and the pixel art, well done! At first I didn't realize I could shoot through walls. I like the venting, and the music. Well done!
Well, the theme was bugs. And that is a bug! Someone (totally not me) forgot to set a layer-mask on the weapons..But glad you still enjoyed it!
If you patch the wall shooting, please increase the guard's reaction time, because I lost every fair fight without using that bug XD
