I love that the gameplay was the opposite of what I was expecting - on my first play I was trying to avoid colliding with objects until I realised that was the objective. The audio is a real treat and the graphics work nicely with the mood of the game. I played with the mouse and while mouse-control can sometimes give unpredictable results, it worked pretty well with mine and it was a good experience.
If I had to suggest one thing to improve, it would be to give more negative reinforcement when you hit a bad object, so it's easier to intuit when you're doing something wrong and avoid it.
I like to imagine what jam games could be like if they were extended into bigger games and I could definitely see Kobald's adventures growing with different game types, locations and activities tied together with a story.
Good job team.
