I think a tutorial would've helped at the beginning, but overall good job! Visuals and sound fx are pretty well done :)

I liked the sound and music and idea but found the game a little confusing.

I really appreciated the graphics and self-made sound effects, very funny. I was pretty confused at first, but the concept is solid.

Hey, really original idea for football! Congrats 

Honestly i didn't know what to expect going into this but i like it, i love the sound effects they gave me a little chuckle playing through, reminds me of a football game i used to play on Mousebreaker back in the flash days. such an innovative game 

Interesting mix of 2 concepts. At the beginning I wasn't sure what the goal of the game was (the ball sprite isn't very clear in my opinion), but once I got it it was pretty fun!

Congrats.

Good game, unconventional rules for soccer, but I worked out how to score and won the game. It wasn't clear what most of the powerups actually did or why healing would be useful since you seem to be immortal anyway. The music is chilled out and the sound effects are... interesting.

I need a tutorial level to teach me how to score. Tried jumping into the opposing goal with the ball, does not work.

this is a fun idea with some great enemy ai! the controls were a bit hard for me, since O and space with my left hand was a bit awkward. i think wasd, O, and space would be fine though. my only other note was the first time i played, the opponent looked like my character and this was very confusing at times. making the opponent more visually distinct (maybe making them a different colour?) could help with this. overall, really well done!

The idea is fantastic; I love the retro look and the animations. The sounds are cool too, haha. Looking forward to trying it again if you add control changes. It's true; it gets a bit challenging. Anyway, great job! ^^

Unclear as to what the goal of the game is. For a soccer game I would assume the idea is to get the ball into the opposing goal but that did not give a point.
I would also recommend having a different control scheme. WASD should work the same as the arrows and O as an attack key is highly incomvenient, I would suggest choosing a key that is easier to access because now my left hand was used for attacking but that made jumping very awkward.

The visual style is pleasing and the audio is well done.
