I went to go and play Dr. Bacteria to practice getting a higher score, and found something incredible; after the cycle where your score is ~042400, the game no longer speeds up. I was able to play the game at its highest speed until 070200, where I made a small blunder. Theoretically, the minigame can be played indefinitely, because the speed at which it goes never extends beyond human capability due to the cap. I can definitely see runs of up to 10 minutes for this endless game, for those who are able to focus on the game well-enough. Perhaps even an hour, haha. Because Dr. Bacteria EX actually has no end, what should happen with the category should an entry be submitted beyond the final Tempo Up?

Hey, I noticed that compared to the DS console, the 3DS console runs Shoot-Em-Up at its full frame rate, regardless of how many explosions or "barely" hits are on-screen. I don't know if the lag during the game on the DS causes any changes, other than lower framerates causing a lack of clarity at times for visual cues (which I don't use anyway), but does running this particular minigame on the 3DS have any advantages? Can we test this?

Not a bad idea at all. Shorter categories, and would definitely be more enjoyable for some (the early minigames bore me a lot, and it even deters me from wanting to run this game if I have to wait to play the more engaging minigames).
