I was a bit annoyed about how the P.R.I.D.E. system worked - achievements - because I had to enter all 12 levels by hand (how many things you need to do to get the different achievement levels) and that was a bit cumbersome. Now it's a flat growth curve, if you need 1200 kills to get level 12, while before it might have went 10, 50, 125, 300, now it will go 100, 200, 300, and so forth. Achievements aren't that important for a normal 100RTBD playthrough, but they have to be obtainable without frustrating the player too much, since you'll need 100% achievements to unlock some story ending stuff.
Also, the lightning gun isn't completely done yet, but I like what I have so far. It's not shooting chain lightning - maybe I could make it leave a trail behind - but it's bouncing between enemies and while it shoots slowly, I feel that it could be useful for certain rooms.
Time spent on the project so far: 439 hour
Currently working on: Making the volt gun and fixing the achievements
