Yeah, definitely more playtest would have helped! Thanks for pointing out the difficulty.
And good feedback on the 'dying randomly'. When they become empty of energy they die, it is part of the mechanics, but it lacks feedbacks at the moment. I still don't know how I'll solve this one. Maybe I can just remove it haha, let's see.
And good point on the manual callibration too, I might have to simplify the steps. I still don't get what you mean by 'automatic'. It is theoretically impossible to get the exact delay of a player's full PC setup. But there are some techniques like making this adjustment under the hood while the player is playing something, which is a good path, but requires a lot of work to get right too. It might be worth, though, if I keep working on the project. Thanks for the feedback!
Thanks a lot for playing and the time to give your constructive feedback!
