the game is BAITO HELL, not BYTE HELL. BAITO = ARUBAITO = part-time job(s). you take "jobs" (shitty minigames) to earn money to buy tools, more games, etc. etc.
from what I've seen, the game seems interesting, if not worth $40. it's also pretty damned funny--for example, the pictures at the top are from the ramen timer "tool" you can unlock; the guy and girl flex/bounce around for 3 or 5 minutes talking about how delicious your ramen is going to be! atsuatsu RAMEN MASSURU
there's another tool where you can put the PSP in front of your face and call up different "eyes" and use L and R to blink. it looks really amusing.
the minigames themselves seem pretty mediocre, to say the least. one was like simon with burping animals, another was an exercise in counting animals with foreigners who mix up their -biki, -hiki, and -pikis. another game had you trying to guess a girl's phone number in 7 guesses. despite the game's medicority, the "tools" seem pretty funny, at least in a "show people and everyone laughs for 30 seconds" sort of way.
also, the minigames are SUPPOSED to be terrible--the game has "HELL" in the title and it's the followup to some PSone era game which was a collection of kusoge (shitty games). so...it's hard to really fault the designers for putting shitty minigames in their intentionally shitty game. still hard to justify spending the money, though.
if you like crazy wacky things, keep an eye out for it when it hits $20 (which should be very soon)
