Alright, I optimized the first stage, managed to get a silver coin sooner, and did the second stage.
First and Second Stages
I included a savestate to skip the intro, for the heck of it. Now, some good news and bad news.
I believe the Silver Coin drops depend on what moment Wario breaks the jar/kills an enemy, and what buttons happened to be pressed at the same time. They're rare drops, though, but I'm going to try and manipulate them as much as I can so I won't have to stop to build coins up along the way otherwise. I've also found that Dashing is only useful if used for a certain distance, I haven't calculated how much yet though... And I've also discovered that in the in-stage bonus games, the treasure chest ones, you can manipulate which enemy-face-lock you recieve, thus I can fix it so that each one I get is automatically the first tile the cursor starts off on, to save a few moments. I couldn't do the same with the Map-piece bonus game, though, otherwise I'd make them all 0's.
The bad news is that I'm probably going to have to redo the entire second level, since I realized while doing the bonus game at the end of the second level that I can speed up the way the numbered tiles disappear, which I didn't do in the first map piece bonus game. So from that point on will likely have to be redone. C'est la vie.
Anyway, any comments at all so far?
