I also want to note that it's possible to completely avoid the zombies if you hug the top of the screen. Not sure if that's a problem caused b the resolution scaling or not.
I see this as a mix of endless runner and a plane game like. It does benefit from its simple style greatly. I feel it could benefit from additional challenge, maybe having the player's speed increase the further they survive or having zombies come from both ends.
This is really nice. I like how the background moves. In terms of controls, I feel that the movement shouldn't be as floaty and there should probably be a ceiling to prevent the player from flying out of bounds off the screen.
It's simple, challenging, addictive. I do feel it should be possible to make the ball rise while holding down instead of constantly clicking the mouse. That would make the game more accessible for players who don't have the physical strength to constantly click/tap.
