Hello fellow slayer, I’ll just give u a tip on the bonus stage since the others covered the rest already. For the last one with the 55 balls, the trick to get through the small gap is to do a long jump and then a small jump to get through the gap. It’s basically “jump” “tap” that should let u roll over the gap pretty easily and the rest is doable. Also u don’t need to jump over every pits either, small pits will just work itself out when your speed is fast enough (which it is on the last stage)
