I'll start with this. This is a unity game and unity can do web builds. More people tend to play your game if you make a web build.
Now onto the game. Straightforward take on the subject, but that's alright. The game needs a lot of polish though.
I'd start by moving the camera further back and higher (maybe to do more of isometric feel). This way you'd see more of the street. I'd also like more complex combat system. Some dodge, block, or some way to not get hit would be nice, because once the fight starts, it's just click-mashing the bad guys.
Health pickups could give you more health. Right now feels like they do barely anything.
Keep up the good work :)
