Hello. Sorry you're not enjoying yourself. It's been a hard balance between making things being too hard or being trivial. Early game torches are the most important items, and if you faint in the cave a free torch should be waiting for you at the town fountain. The slime sparkles are to warn you before it eats something, so if you hear it you should have enough time to run over and get the item before it is eaten. The cave-ins need to wait for the player to be near, otherwise they would never be a threat. If you see where one is, with a little practice you should be able to trigger one and get back to safety before the rocks get to the floor.
The no-dig zones are special areas with good treasures hidden with-in. There should not be any gap between the surrounding terrain and them, we are looking into what is causing this. Let us know if you have any other issues or if there would be something that would make it more enjoyable.
