Thank you everyone for playing our game! We have heard every last one of your feedback and have already aggregated every suggestion you all have made. We have since been planning and developing the changes. There was definitely more originally planned for the long 3 minute zombie level but had to cut back to make sure the rest of the game made it to jam. With that in mind, we'll be releasing a full version sometime in the future and we hope the game stands to what it was truly meant to be (and more!)
