Seiklus (Estonian for adventure) is a platform game for Microsoft Windows.

It was created by cly5m, using GameMaker[2][3] over a period of approximately 6 months.

Seiklus is a puzzle platform game made with GameMaker with an emphasis on exploration.

The game consists of various different, loosely connected areas the player has to explore, collecting both items to help on the way[6] and floating "wisps" of various colours; obtaining a 100% collection rate on all levels will unlock the bonus level which is needed to view the ending and credits.

There are various "hostile" lifeforms in some areas, but at worst they only set the player back a little.
