Hey! Loved this game! Got a couple of suggestions!
I liked the randomness of the upgrades by shooting a door, though, it became boring after a while because I have no input into what upgrade I get. Maybe, you give a hint of what the upgrade will be?
For some reason, my music shut off after about 5 minutes of gameplay.
Also, after clicking on options (which are lovely!), and pressing “ESC”, the options menu stays up.
