I think removing the turn based aspect of this game would be bad because it contributes so much to the aesthetics so maybe make it so things only act once x turns like spider moves once 2 turns crossbow fires once 4 turns etc
also check out this video. I was able to figure out how to move but I had to check if there was more controls after I saw the spider move out of turn
(I tried to link the video with html but it doesn't work so that's why I edited the comment)
