It's Alright
Passes the time. Overall it's okay, but there are many small problems.
The graphics are pretty lousy, there are a few bugs (getting another invulnerability powerup on top of another can stop the music), and no matter what your speed is, getting to the edges of the map is incredibly hard to do quickly. Then again, this isn't meant to be a fantastic piece of gaming, so for what it's worth it's pretty good.
7/10
(And it's "Hydraulic", by the way.)
