15:39-This is for the third mission which is a score attack where you need to reach above a time threshold before finishing the level. You can use those to score extra combo points to add to the timer.
Can't believe Sonic had to do all his friend's jobs for them, they must be so lazy (Jokes aside, you, Axl Thunder, and Gpro did an amazing job! It's surprising just how close you can get to beating every level...)
dude i had been trying to find ways to open sonics sand hill ever since i first played the game. i watched your video and immediately opened the game to try it, only to get it immediately. it was a very cathartic feeling
Really cool to watch! Mainly Amy's Hot Shelter. I did every stage with every character and only found you could clip through the first door as Tails, but never knew you could clip through the elevator ceiling. I'll have to keep this in mind as I'm making videos of my attempts later.
I'm just sitting here finding it fascinating that they tied specific level mechanics (like Flight Deck's stage tilting, or the spinning activator thingy from Amy's levels) to the character and not to the level itself. I dont know why, it just seems like it would create more work long-term but I'm no vidya game programmer. I just know some mechanics belong to multiple characters, in some cases poorly implemented considering the differeing scales of the characters in proportion to each other, and it would probably just be easier to enable them for all of the characters who wouldn't access them outside of their own level anyway.
That attack you've never seen before is the pain of my fucking existence whenever I fight Zero because of how hard it is to dodge with Amy's floaty ass jump ;-;
The stream was really fun, happy to be there, and happy to see the video uploaded since i missed some parts of the stream, Also you forgot to mention the “You Unlocked Sonic!” Glitch that happened in sky deck lmao
That secret big area in hot shelter is probably to get the bigger fish that I'm pretty sure never show up in the main area where froggy is at most for the A rank mission Not that I knew because I for whatever reason couldn't even beat the A rank mission in Twinkle Park despite having all upgrades (but I think there was something about an out of bounds upgrade for big to make it easier, either that or even with all three the A rank is a nightmare still)
15:40 --- Gamma's first level was originally planned to be losable, & there is a (very janked) cutscene for if you did fail it. This is Probably why they had that extra time, there.

i got one for ya, dead rising but you're only allowed to attack with frank's talents, no items, just things like the jump kick, roundhouse, football tackle, knee drop, etc its a pretty interesting challenge, since people sleep on a lot of frank's talents like the football tackle which guarantees a stagger on psychopaths
4:22 Wouldn't charging up a lightspeed dash, hitting the panel, and then releasing the dash afterwards (timing it, obviously) to reach the high platform also work?
Sonic can go into Sand Hill in the regular game, just not in Story Mode In the Sub-Game section in the menu you can play in Sand Hill snd you'll always play as Sonic
It's kinda weird hearing the random issues with the switching of characters. Unless I'm misremembering, I didn't encounter these kinds of problems when I was using the SADX Trainer (though for Big's case, I don't think there was a collectable Froggy). This was years before modding for SADX had advanced, so there was like the 2004 PC game with its incorrect windowed resolution that can be fixed by the trainer, the closing of the game if you played in fullscreen but alt-tabbed, the only level mods that aren't rearranged layouts are like two for several years, etc.

How'd you spindash with a lightdash charged up though? Is it a TAS run or a mod function? Cause normally it just charges up the lightdash again until X/B is let go.
@@EternalShana theres plenty of mods for it actually! Theres one called Project 06 that people seem to really like. Also I can make ANY game a funny stream. I'll play cookie clicker and get a billion views
I know it'd make for a more bleak video, but the swap mod makes the game behave in ways that it wouldn't normally, and somewhat invalidates any of this- When a stage loads in vanilla, every character has a setlist of objects unique to them. There are many cases where levels characters are not meant to be in are devoid of objects or act transitions making the levels unplayable or incompletable. Ironically this means your little Hot Shelter issue wouldn't be an issue (it would have no doors), but it would still be non-completable.
