-Fixed the UI so it scales properly on small phones and tablets (so it will work on iPads now - but we need to add iPad images). UI also scales into "safe area" of phone (space without notches).
-Corrected some information about artworks
-Removed exit button
-Switched position of reset button to where the exit button was
-fixed bug where art may drop while closing the help screen
-added instruction text to tap the + to drop art
