Short and sweet. There's not much content but it is well polished. And tbh that's an ideal outcome for a game jam.
Its a cute take on the whole shrinking/growing idea and you paired it with a couple fun levels. The assets were mostly from a third party but you've managed to mesh them together well; I probably wouldn't have realised if you hadn't said. Its a different skill than producing them yourself but it is still an achievement nonetheless to make them feel cohesive. Good Job!
