An enjoyable timewaster.
The graphics and the music both remind me of Katamari Damacy, a game I enjoy quite a bit. The levels are fun and engaging, with the Doeo's appearing in ways that correspond with the setting instead of seeming (completely) illogical. And the experience of the game is sure to be memorable, at least for first time players.
The game itself is pretty limited. There are only 5 levels (not counting the boss level), and since the levels always play exactly the same, there's no replay value. It's also frustrating that you need to make an account with Shockwave.com to record your scores (it costs money).
