Found a weird bug where the sound, but not the music, would just randomly stop working. The sound button in the top right corner displayed that the sound was still on, but there was no sound. Also, if I turned the sound off and then back on it would work again for a little bit.
You really need to make some drastic changes to the match making system. I have only ever gotten the same people over and over or gotten someone who 10+ levels ahead of me.
@walkingmyunicorn Starting with 2 hearts when you have upgraded yourself to have more is not a bug, the developer responded to someone else's comment saying that.
Could you try to do something a bit different with the chests? There have been several occasions where I unnecessarily lost health because something I dashed at was killed by the chest and I ran into a spike, or the pause when the chest opened didn't stop my dash and I unexpectedly came dashing out of the pause and ran into something I could have avoided otherwise.
The guy with the purple tie in the first room: "Ah, these new kids don't do it right. In my day murder was the way to get promoted." I loved that, so funny.
