Too easy actually
I beat it on my very first try. Its a good concept, but maybe edit the speed of falling down, maybe slow it down a little. I don't really have much to say though about it.
The game is ok. The graphics could be better but it was pretty challenging when you get farther but whatever.
Could be great...
I like the idea of the game. Its challenging, but that's also part of the problem, its too hard. Most of the time, you can still lose if you don't touch the sides. You get close, but don't touch it, but lose. Maybe look into that? Also, this is more of just my liking, but maybe the password shouldn't make you revert to the level you already beat, but to the next level you're on. And regarding the music, i like the song =] but any song can get bothersome after it plays a bunch of times. Maybe have that song play, but then have a sort of playlist? Hope this helped!
Requires more playtesting
From what I played of it, this game is rife with what's called "fake difficulty"
Not difficult because the situations are challenging or interesting in some way, but difficult because the controls are nigh-unusable.
The game doesn't LOOK that bad, but it's frustrating to play rather than enjoyable.
