This game was entered into the 2022 Text Adventure Literacy Jam. It has some lovely illustrations and uses the Adventuron engine.
You've lost your pet dog and have to explore a spooky mansion. A tutorial helps you out to get started. Most puzzles revolve around EXAMINing things and TALKing to people. There are a lot of cute characters, like philosophical skeletons and silly pumpkins.
It's not too long, but some of the puzzles were moderately challenging. One lasted a little bit longer than I would have wished, but overall this is one of the strongest games in the competition.
