BUMP OF EPIC PROPORTIONS
I found a few other things in the trailer I don't think anyone has mentioned yet. You have to look carefully.
0:20 = I think the texture on that slope next to the space texture is a cloud texture. I saw cloud friction in some other mod I forget the name of. Hmm.
0:29 = On the pink level, in the upper right hand corner, you see an area with some pink islands covering an area of orange and yellow textures. I think those textures are lava textures (where you roll on them you die.) The reason I think that is that there are caution signs near the area, possibly warning you to not fall in the lava.
0:43 = You get a clear view of the ultra blast for a split second.
Second half of 0:43 = On the green laps mode level, you can see a message for a split second saying You will have five seconds upon starting time to reach and stay above Speed 5. Good luck! I think I posted this somewhere else too, I can't remember. I think this is Consistency mode, because you have to have a consistent speed. We already know Hunt Mode and Quota mode, I think this is Consistency mode, and that leaves Haste mode a mystery. Could the Haste mode be the side-scroller mode?
0:53 = Weird red thing at the lop of the screen to the left of the timer. I think it's a gem, but I'm not sure.
1:00 = Look straight ahead and you'll see a random powerup. Also, more cloud terrain in the upright corner.
That's all I've got. I've watched this trailer too many times, but it is epic. I can't wait for more. Thank you if you've bothered to read all this.
