The Abyss

just a chill dreamy platformer i guess - thalassophobia warning (nothing dangerous though).
doesn't include options and controls or objective description yet, so just follow this:

the menu has no cursor so just press windows button to get it back on the menus

WASD  to move, E to interact, space to jump. best played with mouse. jump arcs give a fair amount of movement, some jumps require run-ups and hold space firmly to jump a bit further

collect all 20 gems (E) and return to the doorway at where you spawned, interact with the door (E) and then continue in to interact with the final gem

be careful on the heads of the models there's a collision bug!
