not bad.
i thought it was actually really well made, the difficulty increased just enough to make it interesting, and the mines added some degree of needing to pay attention.
about the language thing...i couldn't read any of the directions either, but it was really easy to figure out. you just drag the fish from his sign onto the sign and fill up the purple bar. =D
i think a translation would be nice though...for those people who couldn't figure it out xD
