Timer keeps running after player completes level

When the player dies, the game timer keeps running.

Checking this again, it looks like the timer stops running when the player dies, but it keeps running when the player completes the level.

Ignore the previous comment - the issue was present upon player death or level completion in the master branch. PR #52 resolved this issue for the case where the player is dead. The issue is still open for the case where the level is complete.
