Got a few opinions on how this game feels to play.
It seems whatever your speed was when you press jump is the speed you have while jumping, you can never move any faster but you can slow down to a minimum speed (which is still moving forward). Being able to adjust the speed of your jump both ways is potentially nice, as it lets the player correct a mistake.
If you jump while pressing no movement keys you move forward slightly. This is wierd, and when combined wiht the fact you can't adjust your jump while moving at minimum speed means you end up locked into whatever trajectory you're on now.
Game feels a bit too strict on when you fall off an edge.
