This is very unique; tying growth, movement and jumping all into one button for something that exceeds the sum of its parts. Despite the simple control scheme (one button) I can see a lot of room for skill expression.
The level generation algorithm could do with some work as getting a good time feels more about getting lucky with the level layout. Some obstacles end up placed a bit close to one another, which leaves little room to correctly scale and position for the jump whilst bouncing back and forth against walls. Outside of these edge cases, the games feels smooth and fun to play.
