My copy finally arrived so I started digging into some of the games, starting with Dragon Spirit.
And wow, this is an impressive conversion! The new sprite work manages to convey the original visuals effectively while making up for the lack of backgrounds in some areas, and like @GraveyardDuck I prefer the soundtrack to the PC Engine conversion. Really admirable stuff - was surprised the cut content in PC Engine wasn’t cut on Famicom.
As for the game itself, the level design continues to be a treat, every area’s design perfectly reflected its visual appearance, with some great gimmicks like the insect nests in area 3 to the vanishing light in area 7. The powerup system felt well pitched as well, dying sets you back but you’re always afforded an opportunity to be competitive again. Bosses become trivially easy when your shot type and speed are maxed out, though.
