Nice "scale" mechanic, I would have liked to see it developed more: it's not very clear which doors I can go through or not depending on the bag's size.
I've also had quite a few glitches (catching objects, visual, forcing through doors, etc.), and found the control scheme a bit complicated, but overall a fun game, congratulations!
Last but not least, you have hands down the best cover image/title screen I've seen in a jam ever!
