Cheese Dreams: New Moon
Nitrome's Cheese Dreams: New Moon is a bouncy physics platformer where the moon (quite literally made of cheese!) has been kidnapped by a race of greedy space mice... and since you're the moon, you'll have to save yourself before you get turned into fondue or a decorative holiday snack platter! The moon bounces continually, and all you have to do is use [WASD] or the [arrow] keys to move it around. Take two hits in a row before the moon can recover from the first damage and you're done for, booted back to the last Sonic-the-Hedgehog-style checkpoint you activated, but wait for its face to turn back to normal and you'll be fine. Space mice are on patrol, but if you can bop them on the head twice (once to shatter their helmet, and again before it restores) you can take care of them easily.
For most people, the controls are going to be the hardest part to make nice with. The continuous bouncing movement is one thing, but how ridiculously springy the moon is is quite another, and having it go zinging wildly around because you got too close to the wall can be frustrating. With all the hazards strewn around, it makes for the type of game that calls for a combination of patience and reflexes, so despite its gorgeous style and animation it's definitely going to be something that appeals more to a niche than not. Elements like moving platforms, wheels that need to be spun in a certain direction, and more are infinitely more difficult just because of the incessant movement. If you're steady of hand and pure of heart, however, there's a lot to appreciate about Cheese Dreams: New Moon. It's a beautiful, quirky, colourful game that strives to be creative with the new elements it introduces throughout, and a challenging experience to boot.
