It's a good idea but...
It's much to difficult. It starts off nice and simple, and then by the second level, it gets really difficult. Level 3 on its own seems impossible, and I dread to think of how difficult the other levels would be. The idea is genius, and I love it, though it should be at least a little less difficult, at least at the start.
Unfair Assult more like
Kept me on it for.....5 minutes because I liked the idea but it was so unfair in the amount of rocket energy you had and the fact every level is the same as the one before it as in every level is going through long thin gaps again and again and again
Laptop? Don't bother.
It's a good game, don't get me wrong. However, if you're playing on a laptop don't even bother unless you have a USB mouse or something.
That said, provided you can successfully play the game, it is excellent and definately worth the time.
Difficult Game
Okay i played this game for 30 minutes, took 183 tries first time. The second 53 tries, the games not to difficult after you beat it once, I think im ranked 4th right now for the day. The game needs power ups which extend the time or let you make two mistakes etc... other wise decent game fun for about 20 minutes if that 3/5.
Right Click!
I was able to cheat a bit by right-clicking and moving my mouse off the screen . Try experimenting with it and it could help with those tricky levels.
