Developer, I'd like to correct you on something.
Re-entering the room the gorilla boss fight takes place after beating it will respawn the required item. I've no idea why or how this works, but it did for me.
If this doesn't work, feel free to call me a liar. It worked for me, and I hope it works for you too, other players.
Have fun!
Update: I have just now finished the game, and man, am I excited for the possible sequel teased in the ending.
Oh thank god it worked! Also, I seemed to spawn the item recently somehow, by quitting the game and reloading my save file after killing the gorilla, but I didn't know what was happening or if others would be able to do this trick.
Also, glad to hear you liked the game :) as for a sequel, I'm probably not gonna do one and instead (if I ever get access to Game Maker studio again) just expand the original (I wanted to make a final area for the final boss fight).
