only found 2 goals
Viewing post in Ellie and Osh: Early Alpha - YOU CAN RUN UP WALLS jam comments
It's good you found those. It's my fault for not explicitly stating it, but the central gimmick of the game is the you can run up slopes and walls. The wall next to the bounce goal can be ran up, which brings you to the rest of the stage. I thought the level design led to that, but sadly you are now the second person of two who was confused by that, which is my fault.
