MT submission charlie and the chocolate factory

timer starts once you pick your game slot and ends once you rescue Augustus Gloop (he pops out of the tube) after beating the first boss.

There are multiple game mechanics, but the game tells you about them when needed, you get power ups when needed (varies trough out the levels) You do not need to collect anything all collectibles are bonus items.

If you get stuck you can always pause and quit the game and continue from the level you wore in, same with if you game over
