Major Changes
NEW UPGRADE ALGORITHM - Every upgrade now has hidden tags that influence the appearances of future upgrades. So, for example if you pick an upgrade that makes random towers appear, you will more often find another upgrade that does something whenever a tower is built. This means synergies are easier to find. However the system is capped on how much influence it can have so it only alleviates the pains of a true random system without forcing you into a certain build.
Each Biome now has its own gameplay modifiers meaning each run will feel slightly different per biome.
There are now several starting bonuses which are randomly selected per run. These can range from more starting walls to free upgrades.
