Love the preloader! :D I'm thinking a 'wait for the old lady to cross the street' would've been even better, but that's not relevant to the game I guess. Maybe something for future productions? Game itself is a lot of fun, I like the modern-pixel type of drawing too, with thick outlines, though I'm wondering how more traditional pixel art would look. The upgrades are fun, the game itself is addictive, and it really is good wrist exercise! Better not overdo it on my first play. :P Wish there was a way to save and continue later, and some form of magnet to draw the jewels towards you or something, overall: great work. Keep it going!
