I think the idea of scaling items up and down as a puzzle game is pretty neat! For me, the most difficult/frustrating part of the game was the timing of taking things out of the scale boxes (I'm not sure what they are meant to be) at the correct time. I think it could be better to give the player more control here, as the actual interesting part of the game is the math puzzle part of it to get the ratios correct. Maybe to add that timing aspect back in you could incorporate the diner-dash action stuff that was suggested in the comments earlier. I think that could make a big improvement. Otherwise I think with some more visual polish and working out some bugs I encountered this is a great entry! Nice work!
