Glad to see the game up and running after seeing the screenshots on Mastodon - that tileset is still fantastic, I absolutely love the water tiles especially. The sprites little falling animation was delightful, and still made me smile each time I plunged to my death
It's a challenging but very fun set of puzzles, with a nice escalation in challenge as the story progresses. Loved the notes, and the way you've made sure the cave system is interconnected (returning to the crossroads stage was great, I loved finally getting to see what was down those inaccessible routes!)
