I have to imagine the bad ending is faster. Why are they on the same board? Other than the murky requirements. Worst case you can just die a few times and not have to do the final fight.

I set different endings on same board, because i didn't found which exact requirements is needed to get a bad ending. My idea, that final battle rank decides, which ending will be, but i have no idea how it's works and i didn't found any info about that. And proably, process of getting a bad ending (dying, lol) could be slower, than fight with final boss. Falling into pit can be time consuming, because falling does not instakill you, just getting some amout of damage.

To get the good ending you need to have banked 500 points or more after the first boss fight. You score points by killing an enemy. Base enemies are 1 point, skeletons and knights are 2, beard boys are 3, bird is 5, 1st final boss is 10. You get a 2x multiplier if they die via cliff and a 3x multiplier if they die via magic. Each level also has its own multiplier, however, each death you take in a level drops that multiplier to the next tier like this:

If you keep dying, the multiplier drops for points accrued in that level. I assume it bottoms out somewhere, but I didn't experiment with that.

I understand this map skips some levels, but I think the others slot in logically here as levels 2-6

Just an FYI if anyone trying to figure this game out is curious.
