This build of the game is an entry for AGDG Demo Day 21.  As such, the following changes have been made:

• A new level has been added to the game, unsurprisingly named"Level 5".
• The gameplay camera has been tweaked in all levels.
• UI scaling now works correctly in 4K.
• Levels 3 and 4 have been switched around to more accurately reflect difficulty progression.
• The level menu now shows your best time and least deaths for each.
• The main menu features a demo day related decoration.
