What an amazing level!
Few Issues:
- In certain places there's lack of save spots. Namely, in ending sequences and in no-run run near the stash where you exchange items, these are the ones I remember.
- If you get to Sword Trial with Climb instead of Double Jump, you can complete it, but get stuck on the way out at x1009y1002/x1009y1003. The best fix would probably be to remove NoClimb wall at x1009y1002. There are also wall swims in this case in the prelude to the trial at x1020y998 and x1020y999. Doing it without Double Jump is a nice difficult challenge.
And congrats on the softlock.
At the beginning of the garden, the grass wall was put in an accidental double corner jump.
I also thought the "trial prelude" screen was not doable as well.
That whole part from the first passage in gardens to the trials was not meant for climb, but the possibility was proven, that's beautiful in a way.
Save attrition was used as a dramatic tool for the regular endings.
For the runless, not as much... in retrospective, the shop should indeed benefit from a save.
