Worse (at least back then), the replayability plummeted a lot. Once the fear was gone, you played a couple times to see all the branches and min-max a bit. Once you did an extreme deathless run, it was as solved-problem as any puzzler (which in a way, it was).

I'm curious what a sequel would look like. If it's a totally different puzzle to work out, it might be interesting.

From the images, though, it looks like it might be a bit more seamless an experience, where expanding beyond the initial burner is possible. That could change everything.
