At its heart it is uniquely manic for a horizontal shooter with fast bullet speeds. Because of this it is surely difficult! Specific bomb placement and boss pattern and enemy formation position recognition is key.
There are no end-clear bonuses and points are earned from enemy destruction, invisible point bonuses and ramming your ship into the environment. Note: enemies cannot destroy you by ramming into you, which is something I do rather like about this feature.
Most of you shouldn't care about the benefit of ramming your ship into stuff over survival play! There are certain spots where you can get your ship stuck into the environment which racks up the points faster. You'll see me do it occasionally in my replay but no where where it brings me into risk.
Black Widow is the best ship as her lock-on shot is particularly effective and her missiles dish out damage as well.
I am posting my replay because I want everyone to try out this game and not feel discouraged in any way! However... personally I rather enjoyed figuring out how to beat the stages and bosses without the aid of a replay. I encourage anyone looking to have that kind of fun with their STGs to do so without.
About emulation: music is emulated slowly but emulated slightly better in later versions of MAME. I kind of grew to like the slow versions myself.
I hope everyone can appreciate this gem by NMK / Jaleco! It plays rather nicely and the stages have a special groove and flow to them

-Fun fact about stage 4 Boss, time it out and watch the sun set.
-Check out the original soundtrack if you get the chance. Some nice tunes by Kazunori Hideya, Manabu Namiki, Hiro
