please allow me to recommend my favourite freeware game (:
eversion is a cute little platformer that might remind you of mario. it’s pretty short and it may not look like much (especially at the beginning) but stick with it. i assure you that it is well worth playing. i also recommend that you play it blind, because it really is best that way! you don’t want to spoil the awesome twist ending, right?
get it here! or on steam because it is on steam now, apparently.
