Been enjoying this after getting over the initial difficulty curve. Having it explained as an almost 'inverse Superhot' is what finally made the endless retrying click for me. Initially I was just finding it really frustrating to be throwing myself into the meat grinder, but for whatever reason, having it couched in the framework of Superhot made me OK with that concept.
Also, it *really* helped changing the controls to the 'Tactical' version made it much easier to pull off the kind of choreography of moves the game expects. Not having to take my thumbs off the sticks just made me feel a lot more in control.
My biggest complaint is the save system. I've not put as much time into it as I would have liked because I never know how much time I've got to budget for me to finish the next level completely. It's basically been a level a night, maybe two if I get an early start.
The other one is that the game definitely seems to lean a bit too much into the 'luck' aspect. Where as with Superhot, I felt like there was some variance in how each encounter would play out over and over, it was generally pretty easy to replicate certain outcomes as you tried to perfect your path through. With Ghostrunner, it's wildly different from run to run. Sometimes an enemy is immediately locked on me and firing right away, other times I'm able to close the distance before they even alert on me. Other times they spot me immediately, but take longer to start firing? It's very inconsistent and I haven't been able to piece out why leading the experience to feel a lot more random than I'd like.
Still, having fun with it! Not going to set the world on fire, but for $30, it is a pretty solid little game with a few caveats to really enjoy it.
