One down. Blackjack stumped me. I'd have to keep notes for that one. I'll go thru them. If you wanna tell me the kaizo levels or one that's exceptional to you, lmk. I wanna break records. I have a few records on most popular levels, now. I think the only tech that I can't do skillfully are midairs. I have executed a number of them but never in game, just practice so anything you have that's going to hone my skills send em my way.
Here's a creator that I came across recently that you may want to follow. He does a lot of speedrun and technical courses that are probably more in line with the skill honing you are looking for.
