Great visuals and great sound work! Quite impressive for 48 hours! The core mechanic was a nice interpretation of the theme. I found it particularly fun when squeezing through small spaces, less so when platforming in larger spaces. Maybe the focus could be more on having a larger default size and navigating through small pipes, possible puzzle potential there. Maybe a more immediate/intuitive way of scaling the different axes could be to use another set of directional inputs (e.g. IJKL) or to hold some modifier button and use WASD. I wonder given the nature of the controls whether the punishing setbacks incurred from falling suits this game.
Definitely develop this further!
