This game honestly wasn't that hard to understand. You told the instructions pretty clearly in the game itself. I have played many adventure games that have like dozens of things to them. I was originally complaining about how the radar went too slow. As the game got harder, I didn't care as much. No, I didn't read that about the space bar.
It's interesting to have a game where you can go at your own pace. You get the sense of racing against the clock, but still having some control. Even the name is cool! This reminds me of the games where you had bounce the ball to collect all the points. The dots just look the same.
