Eh...
You got a 6 just because it was completely original. But the dead end blocks ruined everything. That's what the powerups are for you say? Okay, except you CANNOT click to use powerups once things start moving. Which is where you start eneding them. I died trying to use one. That defeats their purpose. I'd kill for a version with at least half as many dead end blocks and an integrated powerup system instead - where they appear randomly instead of blocks.
