I'm sorry you had that issue. It's really hard to balance platforming sequences for all players who have already completed the game because some people come into mods looking for a challenging but fair experience while others come into mods thinking they will be exactly like main game. Here its kind of a mix of those 2 and I tried putting in as many checkpoints as possible. Each checkpoint should only set you back a few seconds but I do understand that falling over and over again will make you feel like the few second set back is a lot. I won't be updating this mod anymore unless there are bugs to be fixed but I take all feedback I get very seriously, I have learned what went wrong with this mod and I have it all noted for my next mod whenever that comes. But thank you for at least playing up to the point you got stuck!
