Yes, I am aware of that, those are in the WIP tab, as you might have found out, the shadow-style only generates a wall of iron barbs, and the insect style a wall of spider webs, that's because i have only added them to show that they are coming in future updates
If I recal correctly you should be able to turn them off by pressing the 'O' or 'P' button though!

Thanks for the feedback, that is always appreciated!
have fun
