I don’t understand the game

You can't see the hole, but the shadow is still produced. Here is what to do: 1. Go to hole blueprint 2. Edit the only rule the blueprint has and select the "note about this rule". 3. Press "insert response before". 4. Add "If a condition is met, do a response" 5. Make the condition "if this actor is NOT frame 1" 6. Try playing!
