Yeah, you're right about drilling upwards being an incredibly dumb timing. The reason I didn't make it easier during the jam is I didn't want drilling up out of the ground to be more viable then actual jumping, but in retrospect I should have given the player some sort of velocity boost when upward drilling. I think I was thinking something similar with the dash timings - that I didn't want them to be cheesable by normal drilling with some y-velocity-shenanigans, but I honestly feel like it was just because I was grinding out a Geometry Dash level with dumb dash timings at the time, and I felt the itch for more and more dash timings ¯\_(ツ)_/¯
