GBA wishes come true at The Old Well
The Old Well starts with a cute introduction to the game's story and controls, but it's easy to pick up after a few seconds. Avoid the falling bricks that track your position, don't get trapped in a pit, and line up the slabs to progress to the next "level." You can punch, push, and jump over the blocks, so you aren't a complete slave to their whims. There's a limited amount of punches that you're able to throw before becoming tired, but you can get your energy back during the lunch breaks that come every ten levels.
The game plays out like a reverse Mr. Driller, forcing you to constantly move around and climb the accumulating landscape until you can pull yourself out of the well. It's a fun diversion, and you can't argue with the price.
