End sickness is now implemented, you get it from being near finiranium, or having it in your inventory. In the attached video, (recorded before i added the inventory sickening,) You can see how it works, you can actually barely survive it if you have low hunger, but if you heal to a certain point, depending on the level, it hurts you, also depending on the level.

Next features coming up: Electric Camo & Entity Sensors

Also, this video is a bit old, so some of the other things i added will be in future devlogs.

OK I SWEAR THIS VIDEO WILL NOT WORK, YOU DONT GET IT, SORRY
