I think you've found it, the main and checkpoints is related to the fire staff bug.
I pretty much just shoot fireball at the wizards, and it says 'failed to execute script 'main' due to unhandled exception: 'checkpoint' object has no attribute 'mask'.
Oh I see now.. it was open, my zone 3's checkpoint is at the exit's door for some reason, so I'm pretty much started at zone 3's exit when I entered zone 2's exit, on my first run. @@ I was playing on the download version, the web version seems to skip to the exit as well when I reload the game on zone 3.
I pretty much press tab on the level 2?'s or level 3?'s entrance door (don't quite remember which level it was), and I spawned in the fire staff room.. does that help? XD
This is really fun, it took me awhile to get used to the controls. I enjoyed figuring out the perfect jumps timing and the obstacles shifting puzzle. Though my game crashed when I reached the enemy wizards, which was after I just got the fire staff, there's a script error about main and checkpoints or something.. (Maybe because I was moving through levels incorrectly? I was trying to backtrack, but somehow ended up in the fire staff level..) Also using the fire staff on the knights/wizards caused the game to crash as well.. I had around 250+ deaths, the calming music really helps keeping my marbles intact.
I've beaten all boss up until Eros, the path to get back was quite demanding.. once I get up there, I'm pretty much half cooked. and Eros just start zippin and dippin on you. A closer checkpoint would be great. The Voice Acting is 10/10.
My laptop was at its limits still, but thankfully I managed to speedrun the ship and ascend the Barnabas. It was fun. The fast movement makes it quite enjoyable. Though the spike collision always caught my foot. And one time the rat AI went asleep and camp the platform's edge while I was wall climbing 😭👏 But then it fix itself after it kills me. Overall great game. Keep up the good work! 👍
