Before this update, half of the gameplay was making sure you had enough ammo to beat the next boss. That kinda sucked, so I got rid of ammo. As a result, the entire currency and shop system has been reworked, and the whole game has been rebalanced. (Note that you still need to reload guns, you just don't have to actually have any ammo. In other words, guns now have infinite ammo).

This is unrelated, but I should also mention that the default dodge button on gamepads is now left bumper instead of A. This can of course be changed in the control bindings menu.

Anyway here's the fun stuff:

This gentleman will greet you at once you clear wave 7. He's really fast. Watch out.

Arny here shows up 8 waves after Professor Hands, at wave 32. I don't recommend getting to close to him, despite his pleasant, creamy appearance.

The autopistol is an automatic pistol that holds 8 rounds and unlocks at wave 3.

Shoots real fast. Faster than the assault rifle, but with a bit less damage. Use with caution. Unlocks at wave 17.

The funny mushroom is a new starting item that will cause you to grow a third eye when you eat it. If there are enemies nearby, your new eye will fire purple projectiles in the direction you're looking. You can aim it the same way you'd aim a gun. Like the potion of bad vibes, eating more funny mushrooms will improve its stats.

A nice contract you can sign that will give you a massive damage boost at the expense of 50% of your max hp. Unlocks at wave 9.

The Altar is a rare building that can sometimes spawn at the tops of mountains (in the snowy part), or, even more rarely, in the tundra biome. When you get close to it, it will activate and present you with either a stat increase or a gift.

Once you've finished the tutorial, you'll be given the option of enabling hard mode the next time you start a new run. In hard mode, all damage you take will be doubled, and there will be twice the amount of enemies (which means twice the amount of pennies! wow). Also, bosses have a bit more hp.

This is a rare armor set that you have a chance to get when you activate an altar. There's also a small chance for pieces of this armor to spawn in a shop.

Now, instead of being returned to the main menu when you die, you'll get to see a nice little screen that shows you your stats for the run you just lost.

• The achievements for running/swimming/sailing a certain distance are now triggered via your overall stats. Before, they were set using your stats for an individual run, which made getting these achievements excessively difficult.
  
• The more challenging enemies that were introduced in the last update now spawn at wave 24, after you defeat Professor Hands. I don't remember what wave they spawned at before but I remember that I changed it.
  
• Professor Hands now spawns at wave 24 instead of wave 32, so there is now a boss fight every 8 waves up to wave 32.
  
• Increased shop spawn rate a bit.
  
• Lowered the speed of the snowballs shot by snowmen.
  
• Retextured snowmen.
