A couple reasons.
1. Laziness. Straight up, I could've been doing them. I just didn't.
2. This one was a little more controversial and hard for me to decide. Basically, I am sort've a perfectionist at heart. I like to undertake any project I do with all of my ability and effort to ensure the end product is the best I can do. Quite frankly, the Demon Drills of the past are not the best I can do. I don't like to produce anything that isn't my best and I was having trouble finding justification to put in the time and effort needed to give you guys Demon Drills that were my best effort. In the end, I decided that it was worth it to put in my best effort, even if it takes longer to do the drills. I still don't think I will be able to do Demon Drills that are the top top quality I want because of a lack of time and resources. However, I will do my best, and that will be better than what I have done in the past. Hopefully, in the future, I will be able to really go crazy and develop Demon Drills as in depth and enriching as I've been conjuring in my head.
