A quick update to version 1.0.1

Undo button can be now held

Previously, you had to press to undo a move, now you can just hold down the button to undo multiple moves.

Level Brightness

Added new option in Display Settings which allows you to make the levels brighter.
This is off by default, recommended for people with darker monitors who have issues seeing in later levels.

PAR adjustments

Adjusted a couple of PARs in some levels to make them more challenging.
