You seem to get off on making players desperate, even mocking them a little when they die. I hope you've had fun because I haven't. I feel stupid for playing your game when it's designed not just to be challenging and difficult but to be impossible to "win". Even arcade games back in the day allowed you enough control that there was some chance, with enough practice, to get high scores. Asteroids, Missile Command, and Centipede are good examples. If I have to keep starting over, there should be a way to improve, but the controls are bad enough and the experience and health powerups disappear so quickly that I'm trying too hard using cursor keys and a space bar to pick them up.
Some of the worst games I've played are that way because whoever made the game crippled the controls to make it difficult to play. The best games usually gave great controls so that it's 100% how I play that determines whether I win or lose. This game? It's 100% on you whether it's worth playing or just a game of losing.
Why don't you make it into a mobile app like The Tower? Put in lots of ads and make it pay to win. It'll fit right in with games like Top War and Hero Wars. You can even make up misleading ads for the clickbait effect, if you like ridiculing your users so much.
