So I played a couple rounds and the first thing I have to say is the damage is lack luster.
I have been dumping points into damage and nothing is changing. I do not feel like I am getting more powerful. Even getting multiple weapons. They enemies are brickwalls and bullet sponges.

This does not make for a fun or entertaining experience.

The teleporting boss does not give a red marker or anything where they are going and always lands on your character. Its sad really.

The whole multiple point system was fun to mess with, but the lack of progression is not doing it.
I feel like the upgrades are useless.
