the enemies aren’t allowed to spawn or move within 4 tiles of the edges of the rooms, which prevents you from getting killed immediately by something as soon as you go onto a new screen. but you still need real quick reflexes to respond fast enough especially if you’re going fast, which i don’t have- so my technique is to turn when i get into new rooms straight away to avoid anything in the middle i might not be fast enough to avoid. i tried moving that boundary in even further but it looks kind of unnatural having all the enemies only clump up right in the middle of the screen. i think you’re right and one extra block of safezone would make it a little more forgiving without being too clumpy in the middle.
