It is basically complete! It goes on sale Sept 19th, but yeah I'm aware of the color issues. Unfortunately I've been without an artist for quite a while. The next best thing I could do is darken every tile that is a ground tile and see how that comes out.
As for the mines, I did improve them more than they were originally, but maybe they need to blink faster to show their threat level?
Easy mode currently only slightly reduces enemy walking speed, reduces enemy spawn rate from spawners, and makes some boss patterns slightly easier. Any suggestions on additional things I could do?
