I had implemented a HUD bar that filled up and the token spawned very predictably every 7 high fives or something. I changed the calculation on purpose and removed this bar. I wanted it to feel a bit more random and the player to be able to focus on dodging, and then having to plan and improvise when the token spawned, I wanted this feeling of "when is it coming?". Also I did not want a hud bar just for this system, so it was a win-win for me. Currently, each high five that doesn't spawn token increases a chance of spawning by 4%, and when it spawns, the chance is reset to 0%. Sad to hear you didn't like this unpredictability, and thanks for bringing that up. Maybe it is still something to look at and study in future playtests and feedbacks if I keep working on this game. Maybe showing some kind of visual aid when the chance is high so players can manage the expectations better can make this system feel better too.
About the counter-intuitive part of the player's body. Yeah, that's a bummer, I didn't factor this would be such a friction. Still thinking about how to make this part smoother.
Thanks a lot for the feedback
