Thanks! Glad you liked it!
Oh dang, that is a way more refined way of doing it! I didn't even think about them changing direction when hitting stuff, i just thought " Uhhh sure, a 3.5 second timer before choosing a new direction should be fine!" (Spoilers, it wasn't, as is evidenced by the way they move and the fact i spent 3 hours trying to make it wooork!)
