I felt that the size changing mechanic didn't play a strong role, each room could be completed at one size without needing to do much thinking. The poor lighting in the maze at the end combined with glitchiness from the camera clipping through walls at the smallest size added an artificial layer of difficulty that didn't feel intentional. It would have been nice to see some gameplay mechanics that incorporated the size changing more directly, and went beyond running and jumping. Also, the rules stated not to use generative AI, and I see that you're using an AI generated image as your thumbnail. It might be okay, since the thumbnail isn't exactly part of your game, but I would be careful with that to avoid disqualification.
