Got addicted! Couldn't close the page until I got to the end. Upgrading was a great feature and user experience with all the indicators of where the power is and if the monsters spawn in the black and a revealing minimap (!). The art is so cute and fun too :D Only thing I would add is visual indicator in addition to the sound that the gun is loading (like a filling bar or the gun starting to change color already during the loading). I didn't understand at first that I had to hold the button even longer than I tried. But that's just nitpicking. 10/10 jam game!
