Just finished playing your game, FruitGhost!
Rules and controls were simple, but enjoyed the creative challenge of solving the levels. A little confused about the icon in the left eye of the skull, but the puzzles could be solved without! Died quite often, but didn't get disparaged.
Would be cool to see a death counter and a key counter (how many halves of keys collected). Maybe some death noise from the skull when the character dies. Could really delve into the lore aspect of the game.
Looking forward to your next game!
