Means that I just made prototypes for like 7 years lol. I did a VR game that was 95% done and the platform (google daydream) got canned. Was a 2 year long endeavor to make it. So after that I kinda just played around with a bunch of prototypes left and right (of my own). Naw your never to old... I'm 40 now and making my first game... just start the biggest barrier to entry is self doubt all you gotta do is try and you will get there!
Good for you though, I definitely would've gone nuts if I got that far, only to hit a wall. BTW, being old is only the initial hurdle (and hardly the biggest one) laziness is the one that stops me dead in my tracks, and procrastination is never far behind as a "just in case". I actually got your game yesterday, just about to spend some time with it (but I already know It's great)
