Considering the limitations of flash and browser games, I can see why the developer sacrificed some of the eye candy to get the most of the physics engine.
Many indie developers nowadays also lower the graphics to get the most out of the gameplay.
Mechanically, this game is quite challenging to play since in every level, the gravity effect changes, followed by very nice colour theme alternations.
The doors to the end of every level are well hidden, which contributes to the overall challenge, and when you do die, the game brings you back to the start, also making the gameplay harder.
The final level carries a great moral lesson: No matter what we do in our lives, we are all destined to die at one point.
To sum it up - Great game, I'd recommend everyone to play it.
