Games that challenge the player with critical thinking to solve levels. 

An American-based, globally-available crowdshare service, Kickstarter offers independent creators the chance to fundraise from their audiences. If a work is tagged "Kickstarter", it likely has run or is currently running a crowdfunding campaign on Kickstarter's platform to help pay for its development costs.

Games where the primary goal is keeping the player character alive under harsh circumstances such as dwindling resources or a hostile environment.
