I really like the mass management mechanic! It's interesting how you become easier to maneuver while smaller, but you usually need the mass for later in the level, very cool design-wise! I also like the blob physics, though they sometimes glitched out for me. The blob does feel a little slow and sluggish to control, though, and I couldn't figure out how to get yeeted without losing all my health on the second level. Also wish it was easier to place blob pieces on pressure plates. With some refinement, though, I could see this main mechanic really shining! Great work!
