The highlight for me is how heavy the ball feels. The game itself is really fun and I managed to beat it without any trouble. It's a shame there aren't a lot of places where you need to use your friend to get somewhere as he pulls you so strong - it would be a super interesting movement mechanic. I also believe the game could use some sort of health system - insta death seems a bit too harsh, but then again, I had no trouble getting to the end.
Overall great game, definitely one of the top games of the jam!
