Really interesting concept, I love the idea of using the higher or lower clicks to control speed. Unfortunately in practice I found the controls very difficult. The amount higher or lower you could click seemed very precise. Instead of going down by a certain amount each time, sometimes when I wanted to slow down a bit, or what I clicked too high it would just drop to 0 and stop which was very frustrating. Definitely a game that could go far though, and would work really well on mobile where you can tap the screen
