Keep at it! As you may have guessed, the shell toss after the two fireballs can be successful whether it goes left or right, depending on where you release it. I had a ton of trouble every time it went left, but after finishing the level I watched a tutorial by Glitchcat and he showed a good spot to drop it so that you'll be safe either way. If you come down from the second fireball close to the wall and drop it there, the shell will pass through you if you get a left-side release and you won't be harmed. Or you could do like me and just keep trying until you throw to the right. 😑 The next bit is SUPER TIGHT, I think it helps to land on the platform with the green shell as far left as you can - you'll gain time on the saw while you're running to pick up the shell. And of course, you have basically no time to waste on the shell jump. Finally, make sure you fast-fall (let go of jump) once you've cleared the spike, so that you hit the falling platform as early as possible. After that, it's just a question of keeping your cool, since the last few bounces aren't all that hard. I think I cleared the level on the fourth attempt where I managed to get back on the saw after the shell jump...it's just that there were a whole lot of runs in between where I didn't manage to get that far. One thing I can guarantee you is that you won't have too much trouble with anything past Sawrfing, because I finished the rest of the game last night! There was one level in the star road that I found really intimidating, and which required some janky falling yoshi physics that I didn't know about, but in the end I cleared it in maybe 30 minutes. Overall, I definitely enjoyed Quickie 2 more, but this was a fine, uh, prequel.
After that, I spent 20 minutes peeking at some other hacks, but I didn't commit myself to anything. I tried Korosu Mario, where I made progress relatively quickly on the first level but didn't finish it. Unfortunately, that game uses stock music and it plays the full death jingle every time you die, which then causes the music to restart. Maybe I've been spoiled by Baby Kaizo and the Quickie games, but that alone might keep me from playing this one (or at least playing it with the sound up). Next I moved on the Gracie World, which at first blush seems like a step up in difficulty from what we've been playing so far. The first level didn't seem too bad, until I realized that you need to collect a shell from a floating coin block that I was using just as a platform and bring it to through a series of bullet bill jumps. Not impossible, but a little more intimidating than the hacks I'm used to! I'm also still considering going back to Quickie 2 to see if I can eventually finish it in under an hour. But mostly I think I need to take a break from kaizo, because I seem to have hurt my left thumb from jamming down the run button so hard playing Valdio's hacks. Go fast, don't hesitate, bruise your thumbs!
