I have received lots of messages in the past regarding a very common game crash. This hotfix fixes that crash as well as drastically improves some game balance I had issues with. A brief changelog is here:

• Fixed worldObject.yy is not defined game crash.
• More than quintupled ore spawn rates and spawn amounts.
• Bomb costs reduced.
• Discovering a cave system now lights all tiles within that cave system.
• All sling drive costs reduced
• All compass costs reduced
• Green Pickaxe copper cost reduced
• Green Sword copper cost reduced
• ...
• probably something else too!
