    Performance Update

    Rerolls have been added to level up screen! Every level you gain half a reroll per wyrdness level. Rerolls are also gained from skipping. Graphics setting is added to options! Enemies have a combined bullet cap of 30. If the current bullet count is close to cap enemies will combine all their pellets into one large bullet. Lizard fire rate is decreased and damage is increased. Removed lots of unnecessary polys on enemy models! Bullet lifetime gets shorter the closer they are to bullet cap. Bullets will stop splitting when close to bullet cap. If a perk has over 5 triggers queued up it will cast the perk at 5x power for the cost of 5 triggers Enemy corpses are destroyed after reaching negative max hp. Worms move quicker! Slo-mo is activated when frames get very low to reduce frequency of costly operations. Lots of bug fixes! Thanks for the bug reports and suggestions!

    Breeding Rework

    Breeding changes Gun breeding now has more strategy than just piling every stat on a gun! Mutation chance has been removed and replaced with mutation capacity. A mutation is an allocation into a stat. A guns mutation capacity will be: the average of its parents capacity + (3 to 8). When a gun is born it will adjust its mutations to fit its mutation capacity. The mutations from both parents are added together. If the mutations are still less than capacity then it will randomly draft mutations till it reaches capacity. If the mutations exceed the capacity then it will randomly remove mutations till it fits. The strategy now is to breed similar guns with desired mutations together. But not too much because one stat can flush out the others. Other things 12 backpack slots! Added small breaks to 5 minute marks to give a breather Recoil is more violent but recovers faster Impact effects are juicier Sounds that repeat often have been given small variations UI tweaks Bug fixes

    General Update

    Content 5 new gun mutations! New visual effects for hitting and criting enemies. Improved visual effects for blood, novas, and muzzle flash. Unique sound effects for orbital beams, novas, and the pulling effect. Stability A perk can only trigger every .2 seconds instead of .1. Excess triggers are queued up. Explosions can only damage terrain every .2 seconds. Special stats on guns are rarer. A couple nerfs to survivor and shotgunner talent trees. Bugs Tons of bug fixes have been made over the coarse of last week. Here are some big ones! Linux and Mac versions are now functional! World generation in extras now works for lower resolutions! Fixed some bugged perk triggers. Lots of optimization. Some quality of life stuff like a skip button on perks and a drop binding. The rough edges are still being ironed out! Thanks for being patient and thanks to those who helped find bugs!
