Really creative design idea c: i experienced some glitches, like merging a small clone to a medium one at one point made a big clone and a medium one next to it, but those aren't a huge issue. My main critique is that the camera works against me, i can't swap to clones i can't see, and the later puzzles feel like guess work since i can't tell what the buttons do when i press them. walking across screens is slow, making it a real motivation killer to experiment and try them all out. it makes it feel like pick-a-pipe basically. The ability to cycle between clones not on screen, or a sprint button would probably alleviate this issue.
Really fun concept tho c: i like the gooey little design, tutorialization was straight forward and clear, and i didn't experience any other glitches besides the one time my clone merging freaked out. great job~
