(Easy & Normal) Alpha Nexus - In-game Timer Exploit (Infinite Hover Glitch)
0Since the stage does not really start the IGT when you move, it does go from 0.0.0 to 0.0.16 but doesn't keep counting until you trigger Saika's spawn, which is nearby the 5th Nail. Because of the way the stage works with the IGT you could skip the 5th Nail and use the Infinite Hover Glitch to continue and skip it until last and complete the stage in around 10-20 seconds IGT. This is obviously is slower than not using it but according to IGT it's faster which is obviously silly. Because of this, it is banned for this specific use only.
It's only banned for Individual Levels, but for full-game runs it's allowed since it's obviously slower and would just waste time doing so. Below is a video showing in how you skip triggering the timer and by-pass it.
