Really fun concept! Especially love the slo-mo.

- I agree that the text is a little long to just jump in, but it made me laugh and set the tone, especially one sentence story of "you're a soccer ball that's been kicked around long enough."

- The SFX are very loud — even when I turned them down.

- on level 3, I think, I spawned in moving and hit like 3 players before I even knew where I was.

- I love the slo-mo. I have mixed feelings about the controls. It took me a while to get used to the right-click left-click thing, and I found myself holding down right click long after I should have let it go. (probably meant I wanted to be in slo-mo more of the time, or at least slow down the regular parts of the game.) I wonder if combining the slo-mo and shoot buttons — so press left-click goes to slo-mo, release left-click shoots — would solve that. But it would introduce a tradeoff to slo-mo, which you may or may not want. Maybe cheat the whole game speed slightly slower to compensate for that.

- some kind of reticule, or line hinting what path your shot will take, would be helpful and juicy. Maybe a focal length change when you're in slo-mo.

I have a lot of notes but I think it's a really cool idea, and I had fun playing it!
