The developer of the game is aware that sliding the spawn tile into a whirlpool can break the level. Ethan and slabdrill discussed it a couple months ago soon after the game's release if you want to read the earliest comments. There is no fix for this right now, so you will have to undo or restart the level.

Yeah, destroying your respawn point and respawning could very well be a loose condition, where your player just disappears and you need to undo/restart. I just made it so that you respawn where the respawn point was last, which in practice is not very helpful either (but theoretically more useful.)

An empty room with a textless bottle note of mermaid noteman just face palming. Or face tailing.
Or just fill the room with shells like the button room of the Stanley Parable but with no escape.
