You are often your best critic when it comes to designing your games. Playing your own game makes you realize what feels right and wrong and what adjustments feel off.
If you want feedback from others though, it helps to make your game as accessible as possible. Think about it from an outside perspective.
Example: Why would I, a random nobody, want to play your game? Why would I want to take it a step farther and provide feedback for it? What would make it easiest for random people like me to play your game? Does it *have* to be downloaded? Can I make adjustments to the game to make it playable in the browser? Sharing it with the right communities?
