Version Information
Steam Patch Notes
Official update history
New weapon: gravity bomb (crate reward, rollable when you have less than 500m hay remaining). This pulls floating hay to the ground. As a result, it will be much less tedious to clear all the hay as the game progresses
"Power Move" can now be purchased up to 15 times
Re-balanced money and upgrades based on player feedback.
New option to make remaining hay glow when there's under 100,000 left. This will help you clean up any hard to see hay patches where the needle might be hiding.
Buffed flamethrower statue bonus from 5% -> 20%
Buffs from crates now extend the buff timer, rather than resetting it. So you can instantly pick up all the buffs you receive without losing out on some duration.
Clumps of hay with less than 1,000 strands, and over 1 meter away from other hay, will fall to the ground with time. This will result in fewer tiny groups of hay floating around that are tedious to clear.
Layout / wording changes to the skill tree to help with clarity
Add small visual effect to Electric Aura
Add tutorial hint for toggling "Auto-Hold" feature (saves you having to hold down the mouse to clear hay)
More money: 50% more money from coins
Electric Aura: Increased range of effect & Significantly increased effectiveness (500 -> 10000 hay cleared)
Improved performance of Homing Animals
Fixed issue where money was not being earnt on the game mode with all upgrades unlocked and standard mode
