Hey guys, it's just that the stickman can spaws things like acid, lava, plasma, I think that's a little.......non-realist. It could spaws lava then kill himself.
Think of it this way. If I were to drink acid right now, it wouldn't kill me instantly - I would have to wait for something vital to be disrupted (which would take some time). Eventually, if I keep drinking it, it'll kill me, which is the same as STKM's behavior.
