there is actually more stages, but due to a glitch currently in the first stage, if you don't kill all the three skeletons in close proximity to each other the next stage wont load, meaning you need to kill all three skeletons in a short timeframe of maybe 10 or 20 seconds starting from the death of any one of them, before a dead body of one of them disappears, i am extremely sorry for this weird bug, hopefully you will play again and kill all three skeletons to unlock the rest of the game, more details about the bug are in the game description before the controls section, again I am extremely sorry for such an inconvenience and hopefully you can enjoy the game to the fullest!
