Chaffinch Challenge is a decent action game by Pete Bunting which features retro-style graphics and a variety of chiptunes for each stage. In it, your task is to guide the frail little bird into the bowels of the earth and beyond while collecting glowing crystals to fill your power indicator.

Use the arrow keys to direct the protagonist while avoiding walls, trees, clouds and just about every single object in the game. Requires a fair amount of arcade skills to complete. Click on the screenshot to begin downloading the file. Seven levels in total.
