the enimes are to hard to kill

Having enemies home in on your position is bad. They should just roam around.

Just some recommendations that I'll leave here:
~Make "Isaac" look a little bit more like Isaac.
~"Isaac" feels like he isn't turning on the center of his model.
~"Issac" fires bullets from his crotch, if you can't make him fire higher than make his model smaller.
~The "Dips" are too fast, they also shouldn't run straight toward "Isaac"
~I don't know if the monster in the next room after the dips is a "Squirt" or a "Dinga", if you tried to make ether, all you made was a bigger dip with the same qualities of a normal dip.
~The spikes do a lot of damage, 1 heart damage is enough.
~The enemies after the "Bigger dips" do crazy amounts of damage too, just lower it a little.
~"Mom's" foot should have a heel on it, as well as a shadow to show where it's going to land.

Sorry if it seems like a lot to ask, it was just really bugging me.
~Speaking of, why aren't there any Fly enemies?

You know what, just ignore this, it's way too much to ask for anyway

Enemies are hard to kill and are way to fast. Plus, they attack immediately.
