One of the most notable games for the Wonderswan, a shmup with a scoring system revolving around killing enemies and not dying or shielding. Because areas are completed when you finish off all their enemies, and the bonus is higher the faster they're completed, speed and score are similar goals for this shmup.
Don't be fooled by it being a handheld shmup, this game gets very hard near the end!
Information:
-Three difficulty levels, easy normal and hard
-Three 'weapons', wide straight and shield
-The longer you go without dying/shielding shots, the higher your base multiplier increases. It also temporarily increases when things have died recently.
-There is a trick with the wide and straight weapons - they run on timers but their timers are different, so if you use a specific rhythm to alternate between them you can shoot more shots than just sticking with one weapon alone, allowing you to kill faster and score higher.
-Bonus for clearing an area is higher the faster you finish off all its enemies

This game has very hard to reproduce but game-breaking glitches. Maybe it is possible to get a credits warp or level warp from them?
Check out the descriptions of my videos for savestates you can open in shmupmame. For example, load this savestate https://www.dropbox.com/s/1szywtvsi90nf7z/0.sta?dl=0 with rom omegaf if you want to try and get the debug menu yourself (you'll want to use insert to fastforward a lot, probably)
For me the glitch started like this:

And by loading state and running it by again with different input I get different results with low probability, including a debug menu and a debug frame advance mode:

Unrelated to me, a different person discovered a similar glitch that froze the game, displayed ? on the screen, then warped them from stage 2 to stage 1:

Wow, I think this must be the fastest TAS in all of tasvideos history.
I feel like the only way I could keep up with it is if I downloaded an encode and frame advanced it (which I might have to do, hah)
Small correction to the Blue House Skip annotation: You're not standing on the wall for a frame, you're actually standing on one of the crates inside of the house for a frame.
(Yes vote, this TAS is mindblowing)
Are you sure? You literally can't half-finish a TAS and finish it in a later session in MAME-RR? That seems like a pretty big oversight to me if true...
