Not actually. It gets subtly harder with time, not score. Knowing that you get more points by cathching them close to the floor, you can easily get over 5000 points before things get too hectic.

At first I thought about doing that. In fact, the ground colliders are still wider than necessary to acommodate for that! 

However, it turned out that being able to traverse the entire screen in one step like that messed up with the balance and difficulty of the game, making the central part the only challenge instead of deciding where to move and jump. So I removed it, and the game became more demanding, which was my goal from the beginning. 

I wanted to avoid Bloodline's (my last Trijam game) slow pace and provide for a need of constant focus, and I think it worked!
