First submission to the leaderboards for mobile version! c: I usually play on GOTY Edition and the difference between their controls is huge. Mobile lacks any sort of manual speed control meaning that you cannot fly at top speed like in GOTY Edition. This restriction limits the player's ability to exploit the engine and create shortcuts. However, I was still able to pull off a power-up skip used in the GOTY Edition which meant less time collecting other power-ups and cleaner flying.
