I just discovered this game, really enjoy it, good job.
I started on Android (FPS ~30) and I noticed that game speed was the same in normal and fast mode
I bought it for computer for a better experience (mostly with UI) and I started to feel something was wrong with game speed.
Is the game speed coupled to framerate ?
Because with 60 FPS (PC) the game is way too fast for me to take actions before I'm dead ^^
On PC (with almost unlimited hardware firepower) there IS a difference between normal speed and fast speed (because it can still handle 60FPS on fast speed)
Not sure I'm 100% clear, but I hope you get it. And a question now, do you think you can fix this someday ?
