this game is good but im gooder

This game feels far from finished.
It's overly luckbased considering platforms can be out of reach, the big rock even destroys platforms, when pressing start you have to switch from mouse to keyboard,the music loop is way to short and there are no animations. The music itself would be okay if it didn't have such low sound quality. This it needs a lot more to be a full game.
You can also add music from newgrounds to the credits when uploading a game so people can easily find the music by clicking the link. (/audio/listen/546858 on the audioportal)
When adding music to a flash, check that it has proper quality. I'm not sure what you made this with but there are probably options for the sound quality when you add it as a resource.

It's ok but it needs some changes for example: the rock didn't hit me but i still died.

king of the hill more like king of the pill right guys

Game is impossible, longest I lasted was 15 sec. Platforms appear too far apart to reach, no score on game over screen, super repetitive music and whats the point of collecting propane? No real goal or purpose, are there levels or is this a survival kind of game?
