Checkpoints, Bugfixes & QoL updates

Bugfixes A number of minor bugs have been resolved concerning level setup, and time travel.

QoL improvements The biggest QoL improvement is a feature to remember the last selected level in the level select screen which is unlocked after a chapter has been completed. This should make going for the best times and zero deaths in a certain level much more convenient.

Checkpoints While some levels are meant to be difficult, they are also meant to be fun. Where possible with respect to the state of the levels checkpoints have been added to remove the frustration of having to do a certain part of a level over and over again.

When first completing the levels checkpoints will be remembered also if the game is closed. When replaying levels checkpoints will be reset every time the level is selected from the level select screen, in order to still have the option to use the checkpoints but prevent having to complete the whole level after dying once when going for a deathless run.
