Wonderful game. This game definitely has excellent sound effects and background music, which makes this game super immersive. Also, the level of difficulty is just right so that player won't get stuck at a specific spot but will have to be super cautious. Nevertheless, the bats in the game are a little bit confusing: sometimes the player runs into the bat and got extra hearts, but sometimes the player takes the damage. Also, I suggest modifying the lookahead parameters a little bit so that the player will feel less dizzy.
