The speed portals are not 0.5x, 1x, 2x, and 3x, they are actually... 0.7x, 0.9x, 1.1x, 1.3x, and then RobTop is adding a 1.6x.
Welcome to TouchArcade! Since RobTop isnt online I will answer your questions 1.Go to http://www.boomlings.com/database/accounts/accountManagement.php 2.You can't... 4. Make a good level!
No, because that would mean we would have even more levels that are super slow, and are considered full levels with minimal decoration. We still need speed portals for different things other than just making the blocks faster. If the blocks are moving fast but the background isn't moving as fast as it should be, it looks weird.
I feel like we still need the 0.5x speed portal anyway. For example, look at level "Echolocation" by TriAxis, and look at the wave part. The objects move slower than the player (as seen on the wave's trail). That's kinda bothers me actually. :/ And beside, if we use that portal wisely, it will makes some level better.
I think the reason RobTop didn't release the sneak peek is because he's having trouble with the song and the song name.
