Run from the Sun
Sometimes these tiny simple games that have fairly simple concepts have elements that make you just keep going at it again and again, to try beating your previous score or go further or unlock everything prior to giving up on it.
Run from the Sun is one such game, all you have to do click at the right time to launch your rocket from one rotating planet to the other.
That sounds like a drag, but with the element of time, a huge hot sun trying to catch up with you and don’t forget the gravitational forces of the planets pulling your space ship towards them and throw you off track, make this game more fun to deal with.
Then you have a few elements thrown in to spice up the game play, planets rotating at different speeds, stars that give you bonus points and also occasional UFO visits when you complete a fair amount of flying time. Talking about incentives, the more you fly, the cooler space ships you unlock.
Its getting hot now, time to take off again! I ended up trying to fly further and further quite a few number of times.
