You play a marshmallow whom a lightning bolt has given sentience. (That may be the best sentence I've written all week.) After making a stirring speech, you fall into a diabolical gravity machine, from which you must escape to save your delicious, delicious kin. To do so, you use either [WASD] or the arrow keys to move, plus [space] bar to jump. Your goal is to make it to the portal at the end of each level to proceed, which is a simple task at first. But add in platforms that swap your gravity around and before you know it you're running on the ceiling, trying to find a way back down, trying to avoid spikes and other pitfalls that would put an end to your crusade.
The controls may be a little bit too responsive in this game. I frequently thought I was just tapping a key and ended up sailing my marshmallow man into a pit of acid, whereupon he exploded into little sticky bits and the level reset. The other main drawback of the game is that there's no level menu. You can't replay a favorite level; you have to go straight through. That said, for fans of the genre it's a must-play, and the quirky-cute story and art might draw in even non-fans. The gravity mechanic isn't terribly new or groundbreaking anymore, but there's still room in it for creativity, and That Gravity Game (yeah, that one!) is a simple but fun experience to put a bit of squishy enjoyment in your day.
