This is so cool, the world feels so alive and dangerous. The puzzling bits of rock/stalagmite pushing work really well. Here's my interesting gameplay tidbit: I had recently entered the outside of the lair, and I saw two dragonlings in front of me. I got surprised by a magma spill to my right that immediately cut off my escape route. I took a couple hits from one of their fiery area attacks and a couple direct hits, but a convenient cascade of the water slick underscores transported me far away from danger. I died only a few steps later, but it's so cool to see these sorts of events come together in a run.
Really, really well done. Bonus points for nailing the true-to-life mechanic of having more money resulting in less anxiety.
