Happy Robot is a game about a robot who is happy. In this adventure platformer game, you have to help the robot find his way through the world by matching shapes, sliding blocks, and other objects out of his way. You must help him reach the end of each level while collecting all of the coins, high scores, and various power-ups. There are also hidden areas to discover along the way. It starts out simple but doesn’t stay that way too long because very high levels will challenge you to use your skills and overcome obstacles with ease. If you have been a long-time arcade player, then this retro-inspired game will be right up your alley!
