Can't recommend this game enough, it's a really good example of how steam's early access should work (updated weekly for over a year). The co-op is a little weird still, and the market is saturated with pixely procedurally generated games, but this one is def worth the ten bucks or whatever it is. I've played it for an embarrassing amount of hours over the last year, and still haven't seen everything.

Fish can roll.

The guys who made this also made super crate box, so I'm sold.

yeah hold on, I need another 100 hours to max out Binding of Isaac: Rebirth
