Hello there, first of all thanks for playing our game. for the bullet can through the terrain i'm still trying to figure it why and make it disappear while it off the screen. i'm trying to make a checkpoint where the player died but it failed. also the pit is the end of the game where trigger a dialogue system. for missing audio and sound, personally i'm sorry because i don't have any knowledge to make any but i 'll learn it in the futures. And lastly Thanks for your kind feedback, i would love to play your game as well :).
