Hey! Thanks for the feedback :). But, that was intentional.
When crouching the player can't move. So as the speed increases over time the player needs to decide when to sacrifice movement and when to A/D to avoid the side flaps. Kind of.
I really liked the game feel this game gives me! It leaves the player with freedom to play any way they want. I would make my plays very fast paced, but as ramidreju said, couldn't find any link to the gamejam theme.
