The origins of this game, whether they are true or not, certainly ring true after having played the game. The reason being, this game handles as if it was designed in the early days of platforming, when game creators hadn't quite gotten the hang of how things should handle.
The movement of your character isn't abysmal, but using the jetpack is far from the joy it is in the previous (or... later?) Dark Void game. You can hold the jump button down to rocket, which is OK for going up, but the delay makes coming down tricky to control, or you double tap, which is probably the preferred method but has some weird quirks, like a slight bob that makes aiming while hovering trickier than it should be. The controls overall feel oddly unresponsive. This combines with moving, which re-adjusts your aim, making you have to do a lot of fiddly jiggering to really point the way you want. All the while, getting blasted by aliens. This could have been fine if it were a dual stick shooter instead, but the way it is makes dodging and firing a real chore if you want to be safe.
And you do want to be safe. Because if you take a lot of damage, you WILL have a "low health" alert. That goes on and on. And is annoying. This just adds to the likelyhood that this game really was created in the 80s.
The entire first level consists of collect keycard, open next door, collect another keycard, which is OK, but again, makes it feel dated. I got to the first boss, and promptly lost all my lives. And yes, since this is claiming to be an arcade game, having lives makes sense, but it feels just like worthless punishment here.
For a bonus, while it's not the WORST music, it sounds like Mega Man cast-offs to me, uninspiring stuff that didn't make the cut for their better tracks.
I guess for me, they either really found this game and decided to do absolutely no modernization, or they concocted a story meant to play on nostalgia and went out of their way to make it play poorly. I really hope it's the first, which is forgivable. The thing about nostalgia is that, people would have had to play the game before now to have nostalgia for it. Either way, poor mechanics without the memories to back them up are a disappointment, and make this game overall not worth it to me.
