I think you should be able to destroy things on your own, so you can delete loops or those little things with the eye
(Anyone there?)
yes lol. You can sort of temporarily delete things if you fling them off the side fast enough. They disappear for a while because they seem to phase through the collider, but if they are the organism things, they end up coming back eventually. Be warned though. They will continue to multiply out of sight were you can't do anything about it and the game will eventually end even when it seems like it shouldn't
