Great game! Reminds me of that old game called Death Worm although I thought it was called Giant Worm at one point. Anyways, this was fun and I had a good time taking care of sea-men (sea-people?). There were a few lag spikes here and there which I think a platform build would help. I think it has to do with the loading of the particles effects. One could try firstly instantiating and starting the particle effect way off the map and stopping it after it finishes a few passes. It can be put above the level node (or even an autoload) so it only needs to be done once. GJ!
