I made a remix to edit, but you messed up a lot of things in there... The damage is going crazy, can check to make sure that the player only gets damaged from the script that contains a bunch or "or" blocks with the stuff that kills it? otherwise it gets tons of damage. say meow I add more later double-click flag
Note: I made the bubbles not hurt him, they are impossible to avoid. Also, you instantly lose health while at the middle of the screen.
