Good job on finding some of the April Fool's pranks! I am surprised no one saw the "ship flat tire" dialogue, the phone in the toilet dialogue, and the purple sun as viewed from Earth. Don't worry, they will be back next April though! As a reward for all the secrets found, I am working on a loot chest system, where you will get elements and various other prizes for completing quizzes. Expect this in the next major update!
