The instructions are available on the game page https://sordidaugust.itch.io/aqz5. If you hold your click/keypress it will keep shooting/moving. Window resizing is not implemented but you can scale by changing the global variables in main.lisp and recompiling. I do not recommend entering the big room like if you owned the place as you will get yourself killed. Your character has enough hp to sustain two bullets. Good luck!
