Has anyone else heard of this game? I downloaded and played it about a year ago. Having searched around a bit here and elsewhere, it doesn't seem to be discussed much.
Youtube Replay 4 Minute Score Attack.
I was hooked on it for a few days, but there didn't seem to be anything more to it than the stage seen in the above video. I was wondering if anyone knew, is there an expanded version of this game (or any other similar titles by the developers, Studio B-Room)? Although it didn't seem all that serious a challenge (massive lifebar), I had a good time using both the mech and fighter forms to clear out the crowded stage unscathed. Seemed like a very fun shooter, potentially.
Apparently there's a Yahoo Japan auction for it, with the back of its case labeled "score attack shooting game" along with pics of only the above stage, so maybe it's a lost cause. But I'm really curious about whether this game was ever expanded on, beyond the score attack mode I played.
edit: or maybe I should look about for info on The Under Stellar 1, rofl.

[THE UNDER STELLAR 2: 4 Minute Mode, Personal Best]
"This is a hardcore side-shooting game from erotic game maker STUDiO B-ROOM. There are 2-minute and 4-minute modes, and you compete to get the highest score within the time limit.
It's like a caravan shooter. There are also EX 2-minute and EX 4-minute modes as bonuses. EX 4-minute is really difficult, and in 2001 I was the only person to have completed it (´・ω・`) To switch to EX mode, enter "ATAMI" on the title screen.
This game was originally included as a bonus with the DVD version of a shooter called Ganburu. The game was also given out on CD at Comiket, and I got my copy from a friend who bought the CD for me at Comiket. It's a rare item now. By the way, Stella 2 is much more interesting than the main Ganburu game (lol).
Stella 2 was later distributed for free as a DirectX 9 compatible version. STUDiO B-ROOM's website is no longer available, so the company itself may no longer exist. I still have the replay of when I won first place, so I might upload it if I feel like it."
