The troll is capable of powerful attacks that can defeat enemies with a single blow, whilst Otto relies on lighter and more nimble attacks. The two would need to work together to solve puzzles. It includes local split-screen multiplayer.
The game was originally going to be published by Square Enix under their Square Enix Collective initiative, in which they ran surveys to see if the public would crowdfund games from independent developers. It was given the greenlight after a voting poll asking if people would support it on a crowdfunding campaign ended with 92% of voters saying yes and 8% voting no.
It was announced that it would instead be published by Maximum Games on 14 December 2016.
