I stuffed my backpack full in the first room and absolutely didn't expect how large the house actually was lol. You've done wonderfully in the art department, both on the sprite/backgrounds and on the shaders, text effects and flair you've packed in (never mind having to do it all in 4 days). The chase sequence was a great change of pace as well!
I don't think I can note any improvements not already commented (my main one would be having value and weight shown in the backpack screen for all items + the incoming one), although I did have a bug where having the backpack screen open while the camera was moving would cause the camera to keep drifting in that direction.
Looking forward to what you'll do with it post jam!
