DoubleShake wasn't on my radar at all but I quite enjoyed the demo! It's a PS1 throwback 2.5 platformer, which shamelessly lifts the quest structure and 2D plane rotation from Tomba, the enemy-assisted double jump from Klonoa, and the grab and shake mechanics from Mischief Makers, combining them into an easy-breezy whole which sees you criss-crossing various islands in search of important whatsits.

Movement's quick and playful, and the Tomba style of exploring 3D space through differently-angled slices of 2D feels unique since we almost never see it in games anymore. Could turn out pretty good if the level design stays fresh across the whole thing!

Also, this is the first game I've even seen with the option to turn on PS1-style polygon jitter as an intentional visual effect. Truly disgusting, but still better than a halfhearted CRT filter if you ask me.
