Now this seems to be a bug I have never really noticed until about last year or so when I wanted to try and 100% Gex 3. I never really tried to do this as a kid, which is why I never noticed it before. Again I've noticed it in the Gex Trilogy, but it's something that happens in the game in general. After all Gex Trilogy just emulates the Playstation games. I've never noticed it in any other level than Gangster TV: My Three Goons and only in the underwater section right before you save Cuz. There's a few enemies that are at the bottom of the water that you need to kill in order to collect all the fly coins. Often times, whenever you do kill these enemies the fly coin that appears after killing them falls through the floor, and you can't get it. It makes me wonder if there's other levels that have this problem and I just never noticed it before since I never bothered to 100% the game. I need to record footage of this but I'm curious to see if anyone else has had this problem.
