I reworked the Seething Heart and Big Head. Both bosses are back in random rotation with the others and are a much greater threat than before. Big Head will definitely kill you.
I adjusted player damage scaling on level. Your damage won't scale as high as it used to based off of levels. The amount of damage that you got per level made every run feel the same regardless of upgrades. Now upgrades mean much more.
I also set a limit on how many summons that the Grave-heart Wizard could have. They can only create five enemies now. Previously this was unlimited.
I made changes to how a level is spawned to prevent falling through the world and sending you back to the HUB.
I added two new corridor types one requires wall running. I will add more variations and randomization in the next day or so. Considering the new dungeon floor doesn't encourage a lot of it.
I'm working on a new dungeon type for the second floor now. I need to put together some new textures for the environment and concept some ideas so expect that to be ready hopefully in the next week.
