I found it really difficult to get any progress at all. In other words, I was stuck in the first point. The swinging felt fine. Tapping the left and right arrow keys was a good decision here, but releasing was basically impossible to time right, and even if you did, grabbing another point was near impossible. The time system seems a bit overkill, as the timer is really high at 400 seconds, and you have a certain amount of lives, making the maximum score limited on itself.
My rating: ★★☆☆☆, mainly because it was impossible (for me) to make any progress. If the releasing and grabbing mechanic was made easier, this game would've scored way higher for me.
