Whooah, that's super weird. I could see how that makes that game, specifically, harder though. They limited themselves, but also used it as a feature in that case, because double jumping after the fall also makes it easier to avoid opponents... So, yeah, for sure, as long as it doesn't evidently cripple the player, and benefits the set of mechanics, go for it.
As always, it's always about how the mechanics are used when designing the level.
yeah
