Quite a good time waster, the way the game "bounces" is similar to a rhythm game, allowing you to work up a steady stream of button presses. Though quite simple, you can easily lose an hour to it if you are not paying attention!
Alas, it is brought down by a few... err, glitches? Perhaps. I am not sure if some of these things are intentional or not;
Jumping from Left to Right goes higher than a jump from Right to Left, which can make it pretty hard to keep a steady rhythm.
If multiple lasers stack, it is possible to get an impossible jump, this easily happens when 3 or more appear at once.
"Cannons" or whatever they are called, the ones that fire a lob of bright light. Well, these things have very VERY random cool down times, making predicting jumps when one is below you very difficult, though, to be fair, it is still pretty rare to lose a run to one.
Character hitboxes are wholly inconsistent, this is easily seen on spikes, when you will not be killed if your feet get tangled up in the spikes, notably though; Getting hit here when landing will kill you. Characters heads also seem to get "unfairly" stabbed by spikes when landing, but I've not seen anything that looks "wrong" when it occurs.
Spike wheels (small) have some rather unusual properties; they won't kill you if they are paused on the side of the wall you are on if you jump. You can see the character jump straight through it, quite strange.
I never got past 700 feet, so I have nothing further to say about the traps in this trap tower.
All in all, quite fun, and aside from the laser thing, there are no jumps that are impossible if you plan two jumps ahead... And I guess it would have been nice if the Unlock-able characters did more than just change your sprite.
