That's just great! I can't stop smiling playing this. Such a fun concept, and I do love a janky physics game.
It is pretty tough though... I understand the task, but sometimes you just don't get the right items to properly hide the contraband. And it feels more like luck when it survives the move, never mind the shake test. I gave it about 10 tries, and only passed once. The only way I know there's a third stage is that one try that was extremely lucky to pass the shake/tip trial.
It's very lucky that there's no rating for difficulty!
Great entry either way. Will probably become my favourite of this jam!
