more little non-intentional things I found:
balloons can be bounced off, and if bounced off to three tiles above the balloon's original spot, a fake balloon will appear 3 tiles higher than the real one, it disappears when it reforms though
at the transformation section, you can press jump a little bit the transform button, and this makes the milk body do some weird things, and gives you a higher jump if holding the jump button. this reveals the fish in the water is killable, for whatever reason
the fish maze has strange hitboxes...
the first lime in the line of fruits is put as a semisolid, I have no idea why, but I assume it's unintentional
if you jump across the fruit gap, you'll find the refrigerator's wall is offset
if in damage animation and climbing a ladder, you'll become invisible
in the second liquid section, holding right as you enter puts you somewhere unintended. You can get out, but it requires a damage boost and very precise movement.
pressing z twice near the hole after the second liquid section softlocks you
I love this game :b
