Reading what is by every standard a professional, insightful and helpful review of our game is really amazing. Thank you so much for playing and enjoying.
I suppose the largest limiting factor was time, I regret not coming up with the puzzles sooner. They were almost frantically designed and integrated in order to make the story work and meet the deadline. For the icon on interacting, I have the sprites ready to go but just didn't quite have the time to implement it. (I also entirely forgot that jumping was something I had done. The trick was to jump up on the Jars, and for those that had already used them it was possible to make the jump from the green boxes. I'll add that to the list of controls.)
Your feedback is truly spot-on. I agree with so much of what you've said and I'll be fixing / changing lots after the Jam. To receive feedback, let alone praise from the developer of one of my favourite submissions to this competition is honestly great to see. Thank you for taking the time to play what we've made!
