Fun little game! I was missing a "continue to next level" butten (or using Enter) and some sound effects for clicking the items. Feels rather polished otherwise. Good job. :+1:.
Also, the items rotated violently after I picked them up. You could consider dampening the rotational force on the first .25 seconds after picking it up or so. Although the rotating also feels like part of the charm and could give a feel for the item's weight. ^^
