I always have my friends play my games while sharing screen and I say absolutely nothing. It's impossible to see your own game as if you knew nothing about it.
Feel free to check out my games as well, I'm very happy with how it turned out :)
I tried your game, and I'm soo bad at platformers. I'm going to try it again later because I want to get better and I really want to see the areas that are in the screenshots they look really cool.
