I got a highscore of 6235. However, on my second try I got 11165. I had a very difficult time trying to punch the enemies into the net because they came in packs and I couldn't get out of there at times.
My 3rd playthrough my score was 684400. I noticed that I could hit enemies from a distance and I can hit the barrels to kill enemies and launch them up in the air. And obviously, because of the health pickup that kept spawning and falling into the level.
Now I did kill a bunch of enemies which is great.
The beat-em up style of gameplay while including the nets for kill multiplier increase (as if I'm playing soccer to kill these enemies into the net) was just outstanding.
The aesthetics of the game wasn't too bad, but using objects as greyboxes isn't a bad idea to make sure your core mechanics are functional and useful for this game.
I did love the up-beat music playing as I was fighting the bad guys though.
I would have liked it if there was a soccer ball implemented and used as some kind of explosive (sort of like the barrels that launched enemies in the air) that kills enemies or powerups that help the player (and maybe punish the enemy too not including killing them, like slow speed, damage loss, etc.).
Also, I nearly forgot to mention this but that start button in the main menu where it was bigger than the quit button and highlighted in red is neat design. Obviously, you probably wanted the player to notice where the play button was and placing a bigger emphasis on that button is a great idea.
