Thank you for playing and detailed feedback!
The game certainly need balance patch to make it easier on beginning and increase difficulty with time. It's cool you found out speed run technique :D
Game is simple (main motivation was 3D game) but gives player choice to find path by patience of just risk by throwing boxes. That's kind of design i wanted to make, give possibility of choice. Of course because of lack of time game is simplified to not punish player for failure.
Congratulations to your son passing the game! That's great achievement! I'm glad game gave him so much engagement to keep doing it :D
After jam I will update game with balance patch and coop feature (2 players locally). That's game that could be funny for family meetings.
