I've also inadvertently pushed swimming entities into the ground by dropping stuff on them, but this is the first time I've seen a super useful exploit in this game.
Unfortunately, this seems like it's a very specific case that can't be replicated in many other levels, but if I find other levels with good clipping methods I'll post them here, and I encourage others to also experiment with clipping.
It seems like you can clip into ceilings by creating a fan, dropping it on Maxwell such that it blows upwards, then using a solid object in the same fashion as in the above post. However, it is incredibly finicky, and so far I haven't found much use for it.
Additionally, you can attach a starite to a rope, cord, floss, leash, etc., and attach that to a metal gate that is blocking it. Depending on the circumstances, this can allow you to cheese plenty of levels.
Rules have been updated to have more clear wording. This does not affect the actual requirements for any categories; the changes only serve to make the requirements for timing and differences between categories more clear. If something still doesn't make sense, let me know and I'll look into it.
