Cool game! Loved how you incorporated the shrinking and growing into the puzzles themselves - they were definitely not a gimmick. As others have mentioned, it was tough to navigate when you were small. But for anyone about to play this game - listen to the devs and PLAY IN FULLSCREEN. It makes running around as the little guy much easier, as more of the room is visible.
Overall, great job! Music was fantastic and super atmospheric. Graphics were super retro. Big props.
