This retro styled game blends puzzle and arcade genres. You control an element which changes its substance as it collects different tokens. Earth element is invulnerable. Water element may be destroyed by fire but allows you to move arbitrarily in or above water. Fire element burns the wooden obstacles but it is destroyed by water. Air element allows you to fly, but you cannot control where it stops. Finally, you should stay away from the "void" manifestations which destroy your element in any form.
