Thanks heaps for the feedback! I spent so long on the game itself that I didn't leave enough for a proper tutorial, so that's what I'm working on now (as well as fine-tuning the audio, UI polish and aiming system), but great point about the slo-mo. I might try a build that uses that kind of alternate control, and let the player pick how they want to play after trying both out for a bit during the tutorial :D
Oh and the respawning will be fixed shortly!
