3/5. As always the gameplay is excellent, I love Burrito Bison, and this would have been a 5/5, but the progression was ridiculously slow, and the cash grabbing was completely shameless.
I'm only at level 15 for both zombie horde and Bob, so maybe I just haven't gotten there yet, but I like that unlike a lot of idle games clicking isn't immediately outpaced by the DPS upgrades. I feel like there's a reason for me to play instead of just leaving it on in the background.
The more I play this game the less I feel like I have any control over what happens, and the more I feel like this is a game of rolling the dice over and over.
