Design flaws are worse than the sum of their parts
I'll start by saying I really like the retro presentation of this along with the rest of the bandwagon. The gameplay puts me off, though, mostly for two features: The way your score constantly bleeds if you go a second without shooting something, and the jamming gun. What annoys me most about this is that on its own, the jamming could have been pretty cool - it would force you to outmaneuver your enemies and make a fast escape to recover, which the narrow passages here seem really well suited for. That would have been a fun gameplay concept. The problem is that it's never going to play out that way because your bleeding score creates a sense of frantic urgency that leaves no room to take your time on hit and run attacks. You've got to be shooting nonstop, or you will die, and so the jamming gun just turns into an annoyance that makes it easy for enemies to stunlock you.
And before anyone says I'm just complaining because I'm bad at the game, I'd like to note that I beat the game. It's not particularly hard once you grasp the way it rewards cheap tactics like camping in a narrow passage between two spawners and racking up huge points. I'm not going to be playing this again.
