ONLY ONE direction: up AND right. :D Nah, but seriously: small, but clever twist on the flappy bird formula. Like how the sub speeds up quite a bit if you hold the key for longer. Definitely can imagine someone with more skill than me to min-max upon this in order to finish the level as quick as possible. Maybe add a timer? However, I feel that the level design rarely leaves enough room for that kind of movement: would have considered a mostly diagonal level with just a few linear parts instead. As of right now, I avoided abrupt movements and tried to move in small, but stable steps.
