I don't know if it was the web build or skill issue but the enemes move at the same speed as the player and can hide under your gun between where you can't shoot them and then it's game over because you can never kill them with their perfect AI.

I just tested something and figured it out
-In fullscreen, the tomatoes were twice my speed
-in the normal view, they were equal
-when I shrunk the page to 70%, they were 70% of my speed and I had an easy time outpacing them
It's the window size messing with things. Worse, the window doesn't scale which means if I shrink the screen to slow down the enemies to a reasonable level I can't pick up the gun to start.
I'll bump the game design score up two because the unfair speed was unintentional.
