Pixelulsar's retro puzzle platformer Ribbitation might not have even heard of bells and whistles, but it doesn't really need them to provide a tidy little experience either. Using [WASD] or the [arrow] keys to move, you play a frog that can't jump, which makes reaching the flag at the end of each level full of girders and ladders a little more complicated. You (and objects you push) can also only fall straight down, so you need to figure out how to climb, fall, and shove crates to get where you want to go. Complicated? Not really, though it does introduce a few new obstacles as you go, such as locks and keys, and hazardous spikes, but Ribbitation doesn't need to pad itself with a lot of extra content to make an enjoyable little puzzle. And we do mean "little", since the game is only a dozen levels long, but while it lasts, Ribbitation is a solid retro title that's great for kicking your brain into gear.
