- Fun and tight gameplay evoking the likes of Contra, Power Blade, and -- bizarrely yet awesomely -- Kirby (due to the innovative jetpack mechanic)
- Truly excellent graphics and sound design, with a feel that reminds one in particular of some of the finest Sunsoft games of the NES era
- That wonderful balance between being challenging enough to hold interest but nowhere near the obnoxious over-difficulty most modern "retro" games are rife with
- Sadly, the music doesn't compare to most decent NES games' OSTs, and is unfittingly quite poor in comparison to the rest of the game's quality. So many fantastic Famitracker musicians out there could have been hired to create a wonderfully composed and fitting soundtrack for this game; I don't really know what happened here, but it's very disappointing.
- The game's over with extremely quickly, even compared to NES games of very modest length, perhaps partly due to how rarely you'll die and be forced to memorize the stage and boss patterns as perfectly as most such games. It might be worth it to crank up the difficulty even on your first playthrough if you're an experienced retro gamer for this reason.
- Cutscenes are completely pointless even for a guy like me who generally enjoys them; simply slapping sprites that are weirdly ugly compared to the rest of the game of your player character and his boss and having them spout one or two very basic lines doesn't really have a place. Either go for Ninja Gaiden-style quality, Clash at Demonhead-style humor or just don't bother.
Overall, though, the fun factor and quality of *most* of the game is high enough that this title is absolutely worth the price tag for any oldschool action/platformer/run-and-gun fan.
