really really great little game, so happy I checked this out! it looked great, played well, and I think was a fantastic justification of the theme and object, better than most. I think they were quite hard in this jam, but you made both parts integral to your game and also very logically sound, so neither felt like a stretch just to tick the boxes! (for the record, I think that's totally fair to do that and again they were hard this jam imo, so no judgement to others, but it's very impressive to make a game where both feel intentional and well implemented)
the only thing I thought was missing was whistle sfx, but with all you managed to achieve in the short time, it's hardly fair to focus on that! if you ever decide to make this into a longer experience, I'll be sure to check it out :)
