Hyperspace dogfights is one of the best 'rausers style shooters on the market right now. I've played dozens of runs and am still coming back. If you enjoyed 'Luftrausers' or 'Jet Lancer' then I highly recommend.

+ Great Action!
+ Plenty of fun mechanics to mess around with
+ Great challenge!
+ Projectiles are shown with trajectory lines. You won't get hit by unseen offscreen bullets
    (Seriously, all 'rausers shooters should adopt this)
+ Good, flexible control
+ Fun, tough bosses
+ Plenty of secrets
+ Easy to learn, high skill ceiling
+ Nonintrusive 'plot' and 'setting'

- Game is very RNG Dependent
- Some important mechanics are not explained well, like 'escalation' and 'coolness'
- Game sessions can drag on quite a while and can feel a bit grindy.
- Game lacks an in-depth scoring system for those who like such a thing.
- Art direction is okay, but was clearly on a budget
- Not much for music, it's atmospheric, but you're better off turning off music and playing your own tracks
- Currency ("SRM") feels a bit undervalued
