So first off wow what a game and you should 100% be proud of it! But I felt the first topic should be bugs to address!
-You can fall off the taller parts, and sort of stop on an invisible platform
-The one monster that I couldn't hit from the topmost platform (I showed you this)
-On the top platform by the stairs theres these bar things? If it hits the airplane ricochets away and I'm lucky I could find it afterwards
-The airplanes can fall into the crevices (though I think they did in fact reappear later maybe test to double check)
-The airplanes can go into the lil crevice NEAR the fire (I believe these were still counted, but still)
Otherwise great job!!!
