A couple of weeks ago, I began implementing a system into the game that both drove the player to complete the level, and to enforce the gameplay loop I had established. I really wanted to emulate the feel of older arcade-style games, where you would restart the level over and over until you succeeded. Typically, this is only seen in this level when the player falls into the lava. However, the new system enforces this rule even more.

With a timer system in place (activated once the player picked up the item at the end of the level), the player will have 30 seconds to sprint back towards the start of the level. If they cannot return within the time limit, they will have to restart. The drive, I feel, comes from the difficulty of this escape sequence. If the player simply walks to the entrance, they will run out of time well before they reach their goal. However, with good grapple mechanics, its more than possible to reach the goal with time to spare. I believe the best escape time I've managed so far was around 15 seconds total.
