Hi! Thanks for playing! We'll be working on the bugs after the jam. The menu and disappearing items are definitely on the list. We'll aslo add the content we had to remove from the game due to time constraints -> this is why you can collect more items than apparently needed. There are 2 more monsters to defeat. If you explore enough you can get a sneak peak of the second one (due to a bug it appears while it shouldn't :) )
The anomaly in the closet is something Lynwood's teacher found and had to consult with his Colleagues. He locked the thing in the closet so that Lynwood doesn't mess with it (yup, the Anomaly had to be protected from Lynwood). The Cupboard had a bright yellow tape all over it, what could go wrong? :)
What it is exactly nobody knows... yet :)
